This isn't a question about whether Mathematica "is mathematics"; no one
claimed that it was. It isn't even a question of whether Mathematica's
web site is authoritative on such issues - no one made that claim,
either. The Mathematica web site claims that there are multiple
definitions in use by mathematicians. The key question is whether or not
that claim is correct, an issue that is completely independent of who
made that claim. The Mathematica web site provides a citation in support
of this claim. Any of the following would be relevant counter-arguments:

1. Present evidence indicating that the cited text does not exist.
2. Present evidence indicating that the cited text does not, in fact,
say what Mathematica's web site says that it says.
3. Argue that the authors of the cited text cited are insufficiently
influential for their use of a different definition to support a claim
that it is "one common definition". This is necessarily a judgement
call, but it can at least reasonably be argued about.

Personally, I'd consider 3 to be the most reasonable target to attack -
I certainly have no idea who those authors were, which places a (very
high) upper limit on how influential they could be.

But you didn't choose any of those approaches. Instead you argue
irrelevancies, like "Mathematica is not mathematics".
