Because every time something new comes along, people will push boundaries while arguing it is acceptable. In this case, they may argue that it is no different from physically furnishing an apartment, taking some photos, then removing the furniture. At least in terms of representing the product. Clearly using AI is much easier and cheaper than physically furnishing the apartment for a couple of hours. Some may even genuinely believe this, seeing it as more a tool of convenience than something that doesn't always represent physical reality.

Probably starts with the most egregious offenders first and then spreads. It'll be interesting to see if other communities follow suite.

Yes, but landlords are inherently evil so if you want to keep the slopulism going you gotta hit them first.
