Can you do something completely unrelated to the question at hand without fulfilling requirements entirely unrelated to the question at hand? No.
That doesn't make the compiler commercial.

You can put your mac application on your website more or less as you've always been able to.
If I forked GCC and made a version where the produced binaries would only run on the machine where the compiler ran, and removing that was a subscription...I'd call it a commercial product.
(Ignoring the GPL issues)
clang is always a cross-compiler, including the versions shipped by Apple.

Fwiw, I find the canned responses like "appeal to authority", "whataboutism", etc, kind of lazy. I'd prefer you tell me why I'm veering off in your own words.
The compiler is not commercial and does not require a developer account.
