Many people said the same thing you are when they started to ban rapelay in 2009, after that the porn game world did not get flooded with bans and it didn't creep into other areas.
It's fine to be unhappy that people did this but don't go over board with the "doom is coming"
That's a very good point. Rapelay was
far more explicitly rape-themed than that No Mercy ever was, yet that moral panic died without extending to other games.
That being said... 2009 is a long time ago. Sixteen years is quite a while, and both the internet and the world in general have changed significantly since then.
To put that into perspective: Tumblr and Reddit (founded in 2007 and 2008 respectively) were still obscure upstart things back then, and smartphones were still a small fraction of the online devices. Patreon hadn't even been founded yet (that was in 2013), Facebook hadn't gone public yet (that was in 2012), and the internet as a whole wasn't nearly as consolidated back then.
Fast forward to today, and we have things like creditcard/online payment monopolies coercing Patreon, Pornhub and OnlyFans. Even though creditcard companies coercing people has been a thing since George W. Bush, the sheer scale of it has only expanded over the years.
On top of that, there has also been a slow but steady rise of anti-porn laws. The UK had its ban on 'extreme pornography' already in 2008, and there have been similar (albeit generally less extreme) bans in other countries since then.
To add to that; banning things in general has been in vogue throughout the West since then. My own country, the Netherlands, banned bestiality and the depiction of bestiality in 2010, raised the drinking age from 16 to 18 in 2014, and is currently in the process of banning fireworks. That might seem like an obscure little example - but it does fit into a broader pattern that extends to the West as a whole. For internet-related developments, just look at how Patreon et al got coerced into banning incest and basically any other kind of (legal!) taboo content.
What I'm saying is, we are seeing things right now that would have been unthinkable back in 2009, back when the Rapelay fiasco happened.
So even though it's good not to catastrophize things, we should still keep in mind that things have changed, and that porngame scandals might not turn out like they did when Rapelay had its fifteen minutes of fame.
