We're not talking about subjective stuff like company culture, we're talking about factually disprovable statements like "you need to be in a physical office to collaborate effectively." That's an objectively false statement and it's irritating to see so many people repeat it.
I don't think either of the posts you've replied to in this thread state that all employees at all companies require physical proximity to collaborate effectively. Just that Matasano (by virtue of its leadership) prefers proximity.
It's entirely reasonable that some people prefer proximity over remote arrangements. People who don't aren't likely to enjoy working at Matasano. That doesn't negate the existence of other perfectly good options for them, as tptacek pointed out.
You don't think that "we prefer folks to be in the office where they can interact with others with less friction" is stating a requirement of physical proximity to collaborate effectively? That's how I read it.
Again: I'm assuming you're this invested in the thread because you really like the idea of working for an appsec firm. I don't blame you! Appsec is an awesome field to work in. I think you'd be much happier talking to Accuvant, which runs an all-remote team, than in trying to talk Matasano out of a carefully-made decision that is a core part of its culture.
I'm interested in this thread because it had so many instances of unstated premises hostile to remote work and I felt someone should say something to set the record straight.
It saddens me that you chose to ignore the substance of my argument and focus on visiting my intentions instead.
