It's not a crime or whiney to want to improve your living and working conditions. For many of us WFH is a huge boost to quality of life so we are fighting to retain it because we dont want to see it slip away just because some higher ups are worried about their real estate holdings, tax incentives, or micro managing. Why just roll over and give up to gain 1-4 hours of your life back per day, saved money on commute expenses, and for many being more productive at their job and being able to work in infinitely nicer conditions than a corporate office would ever be willing to provide.
If you prefer to work in an office than by all means, go in and enjoy it, but for many they despise it and it actively harms their work productivity and life in comparison to being able to WFH. Just because "this is always how we've done it so wanting to change it makes you weak" is a non argument
