NO GOSSIP
NO POLITICS
YOU WERE NOT HIRED TO HAVE OPINIONS OF YOU OWN
JUST CODE
See what happens if you spend more than any trivial time on the job doing something else other than what you were hired for!
The Basecamp policy is now that you can't discuss politics (or anything controversial) on any company platform, including e.g. in the break room, on the discord chat or whatever on your commute, out of office hours, etc. And they are officially removing any feedback mechanisms from company structures, figuratively salting the earth to prevent anyone discussing anything.
Obviously everyone could move to a platform in the cloud for discussions, but the writing is on the wall.
While this may well be a gross violation of labour laws, US employee rights are so weak it doesn't matter: say anything and you're canned.
