Everything uber does is about money and they aren't afraid to flout the law / custom and "disrupt". They swooped in during a strike. They are scabs. They are obviously doing it to grab money. Their CEO is buddy buddy with Trump.
Please don't throw out generalizations like this, particularly as you're a member of the HN community yourself. If you feel strongly about this particular issue, write up a blog post making your case, and submit it to HN, or have someone submit it for you.
The point is you hold a strike to STOP work, not work for less money. That's called scabbing and is the opposite of solidarity.
This is about showing their support to the government, their allies.
