I think the danger of such a policy is that it's easy for those in charge to declare that any complaint or POV they don't want to hear is "political" while the discussions and opinions they approve of are not.
In other words, if people of a particular subgroup of the population were to complain that the company's policies or culture were harmful to them, that might get shut down based on this policy. An example I could see happening is a company with a handful of Deaf employees who ask in the #general Slack channel that anyone running a Zoom meeting could please enable captioning when setting up the meetings. If few people honor this request, maybe the complaints escalate and the Americans with Disabilities Act gets mentioned. Suddenly it's "political" and the Deaf folks are causing a distraction. But really, they are just asking to be put on a more even playing field so that they can actually participate and contribute to the work, but if the wrong person got their feelings hurt, suddenly it's a "political" issue and no one can talk about it, and before you know it, all the Deaf employees have left for greener pastures, and now maybe there's no more "politics" in the shared channels, but the company is worse off for letting themselves become a hostile work environment for those folks.
Is this sort of thing alleged to have happened at Basecamp? My understanding was that it was more politics-first activism, not a response to employees being held back by ADA violations. As someone who works in the field, I don't hear about ADA compliance being treated differently based on partisan affiliation. The ADA was signed by a Republican president, and there are many pro-accessibility folks on the left and the right.
I do understand your general point that it can be difficult to draw lines. I just think that issues like the one you raised would be handled through HR if a friendly "hey can we turn on captioning" message didn't get enough support. I've also never heard of anyone getting their feelings hurt about zoom captions.
But you're right that the people at the top will be the ones deciding what is deemed "political" and what is not. If their definitions don't match up with what the remaining employees think, there could be issues. I haven't heard of any drama since the original incident. Has there been any?
