Uber is an interesting example to me because where I live, it really did revolutionize taxi service. They used to not take credit cards and you used to have to fight for them at the end of the night when bars closed. Plus taxis were usually much less clean than an Uber car. That industry badly needed to be disrupted to make it less of a shitty experience.
On the other hand, I'm sympathetic to people losing their livelihoods because of Uber and am generally opposed to the 'giggification' of everything that Uber seems to have ushered in. It feels like there was a better way to handle the innovation.
