I feel @Rockslayer isn’t a union organiser. Or if they are, they’re a very poor one with that attitude/mindset.

Or maybe they know how to pick their battles? Yeah Discord isn't ideal, but is it really so bad that it's worth the significant effort it would take to try and get people to switch, compared to all the other things they could be spending their effort on?

That's a decision only they can make for themselves. And your condescending attitude does nothing but reflect poorly on you.

Tell me, how do you simultaneously organize people and convince them to use foss? I'm genuinely asking, because we tried to migrate to an open platform and it didn't work at all. We need to be where the people are so we can organize and form our union, not the other way around. The alternative to being where the people are is standing unmovingly on my principles and failing to successfully organize. Don't point fingers if you've never tried it.
