Normally, I'm a free market kind of guy, but FB, Google and Amazon are definitely monopolies and should be broken up IMO. Ironically, the DoJ sued Apple and ensured Amazon would eventually grab 90% of the book market.
Apple is definitely not a monopoly, but they should never have colluded to remove Parler. It was hypocritical considering there was nothing on Parler that wasn't already on FB and Twitter. That frightened a lot of people, and rightfully so, as big tech demonstrated how easily they can eliminate entire businesses (and all the livelihoods that go with it), and more importantly, infringe on our freedom of speech.
