I don't take issue with what you've said about remote work despite very much having the opposite opinion to you because you phrased it as your own personal opinion.

This blog post does pretty much the opposite though; its analysis of remote work is pretty much entirely just generalizations of their own experience, but phrased as if they're objective truth. It was an especially weird editorial choice to make use of the "general" second person given how much outside of that one paragraph was written in the first person. In an article that's ostensibly trying to be humble and vulnerable like you mention, it just comes across as patronizing. I can't say I'm surprised that the author might have been judged for expressing this opinion because it's not about their personal preference, but a judgement of its own.

I think a lot of people genuinely struggle with the idea that sometimes how something is said can matter just as much as what's being said. Being correct and being respectful are orthogonal concepts even when talking about objective truth rather than opinions; if someone asks what 7 times 9 is, there's a difference between telling them "63" and "Well, obviously it's fucking 63, duh!". For a subjective topic like remote work that some people's lives have been quite significantly affected by, it's even more important to put some effort into understanding how one's words will come across, because if the phrasing is poor, people aren't necessarily going to feel the need to go out of their way to try to give it the benefit of the doubt. I can't know what exactly the author was thinking when writing that paragraph, but I also can't distinguish between whether they have the same viewpoint as you but communicated it poorly or if they genuinely think that there's some sort of objective truth than I'm worse at my job working remotely than I would be working in person. Given the amount of care I've put into addressing many of the exact issues they've raised due to needing to work remotely because of a medical condition of an immediate family member, it was quite hard for me not to have an immediate strong angry reaction to how flippant they seem to be with what's at best their phrasing of their opinions. My point is that it's a lot more work to actually care about how one's point comes across than it is to claim that people are overreacting after the fact, and it's worth considering how much of the reaction the author mentions having gotten in the past is reflective of this.
