There's always ways of looking at things negatively:
Stripe = Eat the gift economy and replace it with monetized capitalism.
Cruise = Mass unemployment for truckdrivers, plus inevitable computer-controlled accidents.
DropBox = Oh noes, your files belong to a company and you don't have physical possession of them anymore.
Gusto = [...I'm having a hard time here, people still need to get paid and ADP sucks.] Maybe "encouraging people to start businesses who would be better off in stable employment".
Gitlab = Think of all the potential copyright infringement!
The question is - which negative things do you want to believe? And how do they compare to the positive things the company does? It takes a minimum amount of effort to dream up something bad about a company's core value proposition, but that's not the whole company, unless you put blinders on.
Reddit's incentives are aligned towards a similar addictive loop as Facebook.
Stripe, Cruise, Dropbox, Gusto, and Gitlab are pretty unassaible IMO, though.
