Short version, there used to be a very extreme rape sequence in that bar if Lisa ended up consuming too much alcohol.
I wouldn't say it was that extreme, as such scenes go. There was no blood, no graphic violence, none of the things which are often found in "extreme" rape scenes. And that suits my tastes. Personally, I don't care for too much extremity. Rough, but not too violent is a good fit for my preferences when it comes to rape scenes.
Some influential parties took exception to it and threatened consequences if PaleGrass didn't address the issue.
Which influential parties threatened consequences? If you're talking about Mega and Patreon, neither one of them threatened consequences if PG failed to address their concerns. Both Mega and Patreon simply took unilateral action against his accounts, without warning, and without giving him a chance to address anything. And both denied him any redress of grievances.
To say that they threatened consequences if he didn't address their concerns is a gross misrepresentation of how they acted.
So he complied and in the latest update that sequence was cut out completely.
This is also not an accurate depiction of what happened. PG did not comply with any requirements of any "influential parties." He removed the content in question out of fear of prosecution. In other words, he acted on his own initiative, and not in response to instructions from anyone.
