Of course not. Those platforms have 1A rights. In some cases, the US govt violated those rights by pressuring them to take down viewpoints, hence what I said about "1A violation on the government's side."

In other cases, the platform did it all on their own. That's perfectly legal but is also rightfully seen by users as political censorship, something the EFF claims to fight even when it's not from the govt.

The government compelling them is the issue.
