But it does change the whole feel of a site and make it not palatable to large swaths of users. Because it's one thing if you can say "I just won't follow porn accounts" – it's a whole other thing if the feed is also algorithmic. So now there's a non-zero chance that scrolling through will result in something pornographic? For the record, I have no issue with that type of content, but there's a sense of "time and place" and having it separated.

If not properly gated (via special accounts that can be filtered out, etc, or profiles that have ratings baked in), this can become a mess very quickly.

Yes, a world we've lived in for the past 100+ years.

It seems desperate because, for example, KSA is the second largest investor in X.

Porn is illegal in KSA. So this is going to get a bit awkward.
