Like, I should be able to even berate my employer, as long as I'm not doing it from a persona that's directly tied to my employer e.g. my real name or git handle etc. They might not like it, but they sure as shit shouldn't be able to fire me for it. This would include working on extending a company's products, so long as I don't use the proprietary knowledge I'm privy to.
I realize that this guy published his thing under an alias directly tied to his work. My question was sparked from the general sentiment of your reply - and I am being genuine, sometimes I feel like this stance of mine is somehow "too radical"
I understand that this is not reality in most of the world, but I'm genuinely asking. I'm in the EU and I'm not in the software/silicon valley industry; if that helps with context.
