So this is all just your opinion stated as fact?
Your total lack of structural critique and reliance on relativist takes makes me wonder what your point is? Is it “do what your employer wants you to do?”
This whole topic is a relative subjective thing. If leadership/management feels like their teams' or product's performance is not what they need under whatever model they use currently, then they are at liberty to adopt whatever other model they think will make them more successful. If they choose wrong then boo hoo they failed. That's not an opinion, that's just how things work. Add liberty to dictate your own work location and collaboration habits regardless of your employment contract to the constitution if you disagree (not saying I wouldn't support that lol).
There are valid anecdotes from people being more productive working remote. And there are valid anecdotes from people feeling like remote work has take a toll on their mental health and productivity and ability to collaboratively solve problems. And there are valid anecdotes from people who feel like a balanced hybrid model is exactly what they need. And there's even data that shows hybrid and remote work does improve productivity.
The only opinion I've state as fact is the observation that there does not seem to be one perfect solution for every person and situation and team out there. The only opinion I've truly state is that people should consider compromising on their work requirements because it's silly to rehash an unresolvable argument about which work style is the ultimate global best, ad nauseam.
If I were in charge of this topic at a large company, I do believe this is one of those "every scenario is a bit different" situations and I'd advise managers to work with their teams to make the right call. But I'm not so who cares.
