However, I see a very big difference between a preference that requires other people to take specific action to satisfy, and one that does not, and that's exactly the dynamic I see here. It is that expectation that other people will do things that they prefer not to do in order to satisfy your preference that I see as entitled.
As an aside, I'm not arguing right or wrong. I actually see many benefits to a good office environment (see my sibling comment in this discussion for the problem I have, basically that the majority of office environments are not good). I'm arguing coercion vs. freedom. My argument is that the RTO position is coercive in a way that the WFH position is not, that it's not the same.
I will take several simple example to try and explain how I see this difference.
Consider a Christmas party. I want to wear red and green. I don't care what other people wear. I'm not putting any restriction or obligation on other people. I can satisfy my preference through my own actions alone.
Now consider that I wan everyone to wear red and green. I am not going to be happy unless everyone is wearing red and green. In this example I cannot satisfy my preference without convincing or coercing other people to respect my preference. I am expecting my preference to win out over everyone else. I can frame the argument as "why should their (individual) preference to wear white supercede my (collective) preference that we wear green and red?" It is not the same because my preference in this scenario requires other people to actively change what they are doing.
Now, as you have said, this is not necessarily right or wrong (maybe we're taking theme photos, who knows), and I'm not making the argument that WFH is morally superior or necessarily more productive/better in any way. All I am doing is pointing out that your position is coercive in a way that the opposite is not.
