I was looking back at the GTFO drama and noticed that reviews for that game that criticize Tencent got censored by Valve staff, including my own. Said review stated that the deal itself is a privacy and IT security risk because Tencent is a PRC company and thus legally required to bow to the demands of said dictatorship, including all subsidiaries.

My review text:

Even though they added matchmaking, the devs sold out to Tencent and have been caught censoring complaints related to this.

The reason the Tencent deal is bad is because said company is controlled by the dictatorship known as the Peoples Republic of China, meaning that due to the majority share by Tencent the devs must leak any data they have including sensitive information to said dictatorship on demand, or get the game stolen from them right under their feet. They may also be forced to add PRC spyware to the game as well.

Edit: If you want proof go to this thread, post about how Tencent is a security risk and archive it with archive.is, and watch your comment disappear without warning: https://steamcommunity.com/app/493520/discussions/0/5625537320598621172/
