When you have to deal with quirks (and Adobe just progressively adding more 'quirks' to overcome) to use the programs you need to make your living, your initial claim of 'just use Linux!' still sounds like an unhelpful answer. I mean I use Linux daily but I still need to work in an ecosystem.

Regarding Picasso, use whatever for personal art but people use the "industry standard" so they know any of their colleagues can use my deliverable for anything they should need to is a novel thing. I have plenty of personal experience why deviating causes problems where you least expect it to. It's a shitty monopoly but I'm glad you have a means that allows you to work outside of it (keep doing it, it's a good thing!)
