Yep, been saying this for years now, the vicious and irrational hatred against work from home employees is driven by two main factors:
At a systemic level, despite work from home being obviously less costly in the long run than maintaining an office space, if work from home were allowed to proliferate it basically pop the commercial real estate bubble and then basically every corrupt mayor and idiots in upper management would be shown to be corrupt idiots.
At a more personal level, upper and middle management people essentially get their kicks from seeing busy little worker bees near them, and they would personally have existential crisis when they realize that 90% of what they do is negging and then ommitting or misrepresenting that in actual meetings. Actual meetings which can easily take place in zoom, or often replaced with just an email.
Another part of #2 is they can no longer be toxic and verbally abusive, like they could in person. Anything virtual might be recorded and every email is a record.
Thats a key element as well, the insane corpo manipulation that only exists if you can prove it even though everyone who doesnt up their head up either their own ass or someone elses knows is absurdly rampant... but youre too busy to record it all!
