alt Hacker NewsConsumer activism is trash. Wait until you can't file your taxes without facebook. Not using Uber won't bring taxis back, you'll just end up walking.
I say this as someone who closed my facebook account 15 years ago, and who never opened an Uber account.
One of the points of consumer articulation is to prevent incentives to being "unable to file without facebook". And, where I live, taxis still exist, although as expensive as before.
