I’m new to the party, but I think the dudes attacking you are doing so because in your logic you throw in “and I know how to ventilate a tent” - which, whether intentional or not, lends the reader to think that you assume anyone with a different solution lacks that simple ability. I have no skin in the game, but I do see why someone threw a dart at you. Hey, don’t stab me. I’m just trying to help. We also ventilate our tent properly, however condensation does build to some extent when conditions are just right. It was not the main reason for getting a heater, as our solution to morning condensation was simply to open up the vents, let the wind blow for an hour while making breakfast, and VOILA, dry tent to pack down. Turns out humidity in the mountains is usually fairly nonexistent. If we lived in the SE, or PNW, well… different calculus.
On a side note, I am curious about heated blankets… However in our situation an all-in-one diesel heater has proven quite simple, reliable, hassle-free and incredibly good at drying gear and maintaining a moisture-free tent. Yes, it’s in a Pelican case and was “$1400” but everyone has a different budget, different priorities, different concept of what is “expensive” and what is not. We also enjoy hanging out in the space sometimes in winter time, so piping heat into the bed is very nice.
If we had a lower budget, we would have stuck with something like the Mr. Buddy and a heated blanket, bc even in the teens at 10k feet you can have a cozy night sleeping in a tent - if you have enough sleeping bags and a warm mammal next to you (or two). 
I am a big fan of technology and the constant push forward.
On that note, “making the diesel heater work” did not require any hoops. Plug it in, turn it on, twist the dial… and it does dry gear in a very short amount of time… perhaps faster, maybe much faster, than hanging gear in the sun… but both are adequate solutions. One isn’t necessarily better. I lied. For back-to-back splitboarding days in the San Juans, the diesel heater is better. You simply lack the direct sunlight for enough hrs to dry gear appropriately. The heater solved that for us.
I think it also depends on perspective. Specifically, which direction were you coming from when you installed your GFC? If you were a wheeler, crawler, overlander, big rig camper… getting big, slightly heavy, units to throw in the truck camper may still seem quite minimal and simplistic.
IF you came from backpacking and now have a GFC, a diesel heater and big, heavy boxes may seem to you like having a 5th wheel with a Honda gas generator… so… perspective matters.
Our goal was to have a GFC with basically every “main” feature you can get in a pull-behind, but fully modular, minimalist (relative to actual campers), while maintaining full ability to shuttle bikes and kayaks on crap roads for epic descents. Every situation is different. We refurbished an old pull-behind, sold it, and used the extra $ for the nicer pieces we felt would enhance our experience - such as the Planar / Pelican “all in one” heater. No fuss, no mess, no leaks. Strap it down, hit the road. We also spent a decade on the road, traveling the west, climbing, paddling, pedaling, hiking and spending weeks on end in tents between assignments… we just didn’t have Instagram to share it all 
AAAAND since that decade on the road, we’ve lived in the mtns on the western slope of CO… where everyone knows how to play outside and nobody subscribes to a single outdoor magazine. I kid… some people are still very into the consumerism of the outdoor industry, even out here. What can you do? Many different strokes for many different folks.
Just don’t assume that anyone “not” in the heated blanket camp lacks basic knowledge of how to position a tent in the wind and/or how to ventilate. The Venturi Effect, for example, is not a secret, any more than Boyle’s law… Assuming someone in the “burn that gas” camp is lacking knowledge will get you in a pickle sometimes.
IMHO, if anyone is asking, many people lack proper heated blankets bc the older systems had massive power draws & they were a bit bulky and heavy… not to mention the risk of electrical fires. I am sure the new ones are much better. I would also ask, out of curiousity, what is the average size battery in useful Ah for the GFC crew reading this thread (with popcorn) and what is the average hourly draw of the blanket? I could see some systems lacking enough juice to run them all night. The nicer heaters are reliable, draw around 1Amp/Hr to run, and a single fuel cell will provide 7+ nights of heat.
I would try the heated blanket for the shoulder seasons, despite having a very nice heater. If the Planar could live in the garage for a few extra weeks on either end of winter & burn a couple of gallons of diesel less, that would be a small win for sure.
And while it’s an individual choice for everyone reading, and I do not judge… I came from a science and first responder background SO we felt the reputation of the cheaper heaters carried too much risk for us. The option to wait, and spend more money on a more reliable unit, worked with our risk assessment. Again, to each his own. I imagine the failures are rare and most users will be just fine for many years. We opted to skip that risk.
All of this novela aside, the cool temps of the forum are a reason I come back… SO i hope we do not devolve into drama.
