My company is hybrid. I'm the boss.
I'm not planning on changing it anytime soon as I know it gives my team a better work life balance.
WFH also makes jobs much more accessible to people. We couldn't, for example, hire someone to work in the office full time that had severe mobility problems. We rent an office on the first floor of a building that doesn't have a lift, so the ability for someone to work from home instead can make a job much more achievable for someone with a disability.
We do, however, have one staff member that takes the piss. As a result we rescinded his right to work from home (full disciplinary process). We're starting allowing it again with expectations of performance and attendance, but it is an absolute pain for us to manage and monitor him. We will do so though and will go through capability/disciplinary procedures if we have to as, quite frankly, he's a liability anyway.
I can see, therefore, why some businesses are bringing people back in. As always, it's the actions of the minority that affect everyone else.
All I would say though to you OP is tread carefully. Use the rights available to you to request flexible working, but don't be insubordinate to the requests of management in the meantime (i.e. don't give them any reason to start a disciplinary procedure against you). If your contract states that you are to work in the office and the WFH arrangement was introduced due to covid, like ours was, they are entirely within their right to ask everyone back in.
What effect that has on their staff retention is, of course, another matter.
