Was Parler blocked because Amazon did not like it, or because Democrats do not like it, and they have full control of government, and can pass arbitrary laws e.g. to break up Amazon?

Edit: an unfairly flagged comment in reply to this says > Why would democrats break up Amazon, when it helps them in banning the republicans? That will not happen.

That's exactly my point, this is a form of lobbying to stay on good side of the government.
