I don't doubt that people earlier in their career work better with more senior people at arms length to help them. Hell, I experienced a bit of that my first few months at a new job where I struggled to understand processes.
But after a period of time, I got it. Sure it took longer, but I got there.
Now, I get less work done in the office because people spend time socializing, and more importantly, the workstation is not customized to my liking because of this whole satellite desk situation.
I'll say this: If these companies tanked during the height of Covid, they'd blame it on WFH. Of course, the financial performance for these companies was quite good, so now that there's a bit of correction, they search for reasons to bring employees back to the office.
