Your still don't get it.
Adobe brings the user more value, because using their software users are able to work quicker, finishing more work and earning more money. Adobe subscription is negligible. Freelancers earn more in an hour of work. But save a lot more.
Even people like me, who are for some weird reason especially inclined to use FOSS, we try to dabble in it, every few years check is anything has changed. But it doesn't. It remains the same. Pros can't afford not to use the best software and nothing comes close to ps, ai. Sad but true.
