I could definitely have formulated my opinion better...

If Amazon acted alone, I do not think that there would be an antitrust case. But given that Amazon acted together with the app store duopoly, in what appears to be a coordinated action with the same goal, I think the antitrust case applies. If two very dominant players make a pact with a third not-so-dominant player to squeeze somebody a bit more, it only makes their anti-competitive behavior harsher.

BTW, I believe that Parler really could have prepared better. It is obvious that they did not have a good plan B.

Why do you assume that there was necessarily coordination? In my opinion it's likely everyone who is dropping Parler came to their verdict independently.

It is certainly possible that they all acted independently, but given how many cases of anti-competitive behavior on their part have been documented in the linked report of the Congress - these companies are not completely honest.

Mikhail Gorbachev used to say "Trust, but verify." I would like to see some verification in this case.
