If I don’t like my coworkers, I’m out. I like people who give a shit about the work I do (a.k.a “collaboration”). “Whatever, you own it” is just lazy for “I can’t be bothered to understand what you are working on”.

The problem is not the collaboration, it’s the ineffective collaboration. Maybe the author should fix that instead of pitching magic anti-collaboration click-bait pills.

Also, the problems you solve must be pretty straightforward and unambiguous (or you have a small codebase) if you have the luxury of being able to just make a pull request for it.
