Since I have found it historically hard to engage on this (broader) subject around here, just yesterday I put together my own thoughts at https://loudwhisper.me/blog/proton-fediverse-burnout/
Personally, I did not see the value of their Mastodon presence, it was write only marketing communication, no engagement with the community anyway. That happened only ever on Reddit, which I think is going to continue being the case.
They push the same info via email newsletter, if someone really wants that stuff.
Either way, the post above covers my take on the whole drama, not just this last small chapter.
I completely respect your position. Some people genuinely like the office life and it's totally fine!
Personally, I have never had any boundary issue with home being used for work. I have my own office room that is also my hobby room that I made as I like, so it's a very nice and quiet space, and I love working there.
Besides the obvious aspects of this post which are quite dumb, what that person misses is that by working from home I finish to work at 17 and at 17.01 I am free to go meet people. Cutting commuting time frees quite some time for personal life and not to mention working from home is associated with more flexible work too, like doing some chores during a break etc., which frees up even more time.
