Some plausible excuse can always be found.

Humans are incredible capable at "reasoning" (framing, rationalizing) things to any desired perspective or conclusion.

Those are you words, not the words someone else has said in this thread.
You did say this though:
> There are plenty of alternative platforms, which conservatives are constantly failing to lure anyone to.
The person who replied to this assertion noted some examples of such alternative platforms being interfered with - and of course, a "reasonable" reason can typically be manufactured (imagined) within seconds.
And all of this does not take into consideration that visibility of speech largely varies per platform. No, you do not have a "right" to be on a platform, but that is orthogonal to the question of whether the broadcast of certain ideas is being forcefully limited by the employees or executives of large platforms (completely within their current rights).
