My brother isn't as much of a fan because he has 4 kids and it can be hard to concentrate on work, though better when they are in school. I'm guessing there's also a honeydo list now and again that gets annoying.
As for me, I've been WFH since covid began and I love it. No kids at home (other than my 21 year old) and no more 2 hour commute. No dangerous winter driving on a 2 Lane highway that goes over a mountain pass. No more carpool mates that have super annoying habits. No more packing a lunch to a remote site with no other food options. I could go on.
