In the last 3 years we had government officials directing, in very strong language, various tech companies on what was and was not allowed on their platforms. While many people might argue that tech platforms are not public squares and should be free to censor however they like, everyone should have a problem with politicians directing tech companies on what can be said on their platforms.
As an addendum, I’m always curious to hear what that camp has to say about net neutrality after arguing so vigorously against its core principles.
IMHO if you want to operate as a mass market platform and are pursuing a winner takes all business strategy you should be regulated as a common carrier (Uber, Facebook, Comcast, Google, Microsoft, cloudflare, etc).
