Agreed. It can also be people who have problems with X for other reasons and like to see X “disrupted” (e.g. a disgruntled grad student who got screwed over by a bad advisor or a hard working and capable office employee who got passed over for a less capable, less hardworking PhD holder).

Like I had many bad experiences in cabs in my younger years. It was just bad luck really, but I hated cabs for the longest time because of that and completely dreaded needing them. When Uber was first coming on the scene and cab drivers were protesting against it, I did think to my self something along the lines of “if an app can destroy your business, the problem was in your business” but I really just didn’t like cabs for other reasons. And the irony is now Uber is the same. When I land in my airport, I see crazy lines for rideshare with people waiting on cars to come pick them up, while there is a cab on the other side that is ~$15 cheaper somehow and ready to go with no lines. And I get to tip the driver those saved 15 bucks
