So? We are humans. We get distracted by a whole bunch of things that happen to us daily because, well, we're emotional creatures. When you are somewhere most of the day you end up being distracted by many other things than "just work". If you cut the politics then something else will keep our primordial animal minds busy.
A place where you have to only "be about work" is impossible to achieve. Even sweatshops in Bangladesh have unions and places where they can talk politics.
I would say a healthier choice for them would've been to cut out the people that were bullshitting and causing toxic environment. For sure those exist and should be spotted if they cause negativity at work.
Funny thing is that doing this top-down, as they are doing, is literally "cancel culture".
