I don't know if this has been posted here or not but I've been checking out the reddit controversy surrounding the banning of members from various anime subs and came across this article that was posted in the comments.

It's hard to sum this up because it's a long article. But it's a look at various large companies/sites like Steam, Tumblr, Google, Reddit, Sony, Discord, Facebook, etc and how they've reacted to financial investment from Chinese companies and from trying to enter the Chinese market.
There are a few things that this article doesn't go into like Ubisoft attempting to introduce censorship into Rainbow Six Siege in order to appeal to the Chinese market/regulations and that Devotion game receiving backlash from Chinese users on Steam (I believe this was pulled but I'm not sure if it's back up yet).
It also goes into payment processors as well and the Chinese government's role in this. The segment on Sony is towards the end, and reading this I found it gives new context to the quote "About the censorship, we tried to meet global standards".
A few quotes from the Sony section.
There's so much in this article that I don't want to just fill this post with quotes although I've kind of done that already. This is the only article I've seen making connections between all of these companies and their increase in censorship alongside investments/entry into the Chinese market.
