That is ridiculous.

If I want to paint apples, and you want a painting of pears, it's not ableist for me to tell you no. It's not ablist to iterate out your possible options for getting a pear painting either. And that's what he's done.

Now, the entire painting profession might be ableist in that there are certainly barriers to entry. But it's not a single artist's responsibility to fix painting as a whole.

My point is, if you truly think the situation with raync is ableist, help develop tools so that more people can program. Enable people to program. Don't just shout down the guy who said "go program". That doesn't help.
