The pinned thread was locked which is exactly why similar discussion would resume here.
This is true, but it’s also something that has been alleged on several occasions by its more strident advocates (not me, I actually made a similar objection to yours earlier), to the point where it no longer matters if the comparison is accurate or not, so long as enough people think it’s real; especially if that includes staff.
There has definitely been people off-site attempting to speculate or deduce what games do or don’t have unstated AIGC. If you want examples, you can find them fairly easily. Some vigilance makes sense but they also gave the same sort of wild paranoia vibe as talking about Q-angles and whatnot. I see that as a reason for more scrutiny by staff to stave off any risk of that poisoning the community vibe further. If there’s no firm guidelines/rules on tagging use of AIGC, then speculation is inevitable.
Again, even if some claims are bogus, the lack of trust is damaging for devs and general users alike. If the use of AIGC is a contentious issue, than it makes to at the very least give people that don’t use it some cover from spurious harassment.
