Amazon/AWS made a business decision that very well may be politically motivated but I have no doubt it's fundamentally profit-motivated due to risk of fallout from hosting a controversial platform known as Parler especially with ties to the capitol riots.
The Washington Post, another Bezos owned entity is very much left leaning. And just recently issued a correction for making up complete shit in regards to Trumps call with Georgia elections investigator Frances Watson:
The Post issued a lengthy correction on Monday after audio of the December call between the then president and Frances Watson was released.

"'Trump did not tell the investigator to "find the fraud" or say she would be "a national hero" if she did so. Instead, Trump urged the investigator to scrutinize ballots in Fulton County, Ga., asserting she would find "dishonesty" there. He also told her that she had "the most important job in the country right now."

It linked to a new story about the recording, adding: 'The headline and text of this story have been corrected to remove quotes misattributed to Trump.'
The Post was slammed for the mistake, with journalist Mary Katharine Ham writing on Twitter: 'So, they made up quotes. What in the actual F.'
Twitter user Glen Hilts added: 'Great. And, 90% of folks will never see the “correction”.'
Another added: 'This is disgraceful. People on the left believed this garbage, and won’t even read this “correction”.'
Independent journalist Kyle Becker added: 'The ironic thing is that intelligent people knew this was made-up BS from the get-go.'
