Well, the subscription comes with developer support. (The
self-support option is $99 per year, with the same packages as far as
I know.)

It's not.

That's a question for Red Hat sales. I couldn't possibly comment.

But these products have unbundled support, and you pay only for
software licenses, right? So the comparison isn't really fair. For
GNAT, the equivalent self-support option is priced at a very
competitive $0.

I doubt it's commercially reasonable to support such developers, at
least not without constraining them to a specific (small set) of
target platforms.
