Most users don't care about any of the spying. I'd expect a competitor of similar size to do the same. If there's any improvement competition could bring, it would be for the creators, giving them a larger slice of the ad revenue that otherwise goes to the owners of the platform. I guess that would mean better quality videos for users. Though, I don't think allowing anyone to make boatloads of money by getting millions of people to sit around for hours and hours watching videos has been a positive for humanity. Incentivizing creators with more money will just make this worse.
