I think that your point 2 is a positive when taken in isolation, but with negative consequences for wider society - it did drive other firms out of business.

I also don't know how many markets uber entered were actually monopolies. London certainly wasn't, though the minicab firms there were dodgy as hell. It will have increased standards of service in that market longer term, even as it unfairly competed.

Are cab monopolies a US thing?
