There is probably no point in arguing this further, though I appreciate your input and the manor in which you have given it.

The thing for me is no one benefits from the lack of commitment to some way of working (and I mean a company commitment to something isn't a cast iron guarantee either). It's not like saying we're an in office company we expect you here 5 days a week; for me that would be a massive disadvantage. However, I can see that for other people that would suit them perfectly and might well have lots of advantages in terms of social life and opportunity to learn from those you work with. If a companies stance was that we are working from the office but reserve the right to work fully remote at some unidentifiable point in the future that would similarly disadvantage those people who seek out in office jobs.
