You're missing the core of what I'm concerned about. What I care about is something like "what looking like you're putting in sincere and whole-hearted effort looks like". I oppose publicly talking about how you as a software engineer can put in 45 good hours of work reliably every week and feel like you have good work-life balance for the same reason people make comments if their coworkers over-dress for work.

If you can, and you say that you can, and you don't complain about it, then that becomes expected. This is as true of wearing a suit and tie to work as it is for putting in long hours. Finance is in a really shitty place because of this and I don't want the tech scene to follow suit.
