Easy enough. The question to ask is what does more good for more people? The government is a tool, nothing more or less. And like any tool, it's suitable for some purposes, and unsuitable for others.
The legacy taxis are just utterly terrible services on so many levels. About the only thing they're useful is for trips between the downtown hotels and the airport. That's fine for tourists; but if you actually live here, taxi's are all but useless. Uber, Lyft, and Sidecar show up on time where you need them, don't bitch about trips to or from the avenues, don't play the "the credit card machine is broken, cash only" game, and don't stink of smoke, pee, or vomit. None of that is true of taxis. So breaking the government supports for the legacy taxis is good.
Internet monopolies harm the consumer and stifle the economic development of new and innovative businesses. Obvious and iconic example is the extortion of Netflix by Comcast and Verizon, resulting at first in crippled performance of the service and eventually an increase in the price. That's direct and measurable harm to millions of consumers and an innovative and useful startup business, and hardly the only case of consumers or new businesses bering harmed. The bandwidth monopolies are causing harm and need to be broken. And if government action is what it takes, then so be it.
And on the cops thing, I think what people want is accountability. "Evil and racist pigs" do make it through whatever screening processes the police have for their recruits. When discovered, they need to be punished: thrown off the force and locked away. And when the "good cops" cover for the "evil and racist pigs", refuse to remove the bad ones from the force, and make sure that they are not punished for their crimes and abuse, the "good cops" cease to be good. "One bad apple spoils the whole barrel", as the proverb goes. The bad apples need to be purged before they are able to spoil that barrel.
