Don't worry, Collin, I wasn't challenging your motives.

It's just a difference if "user123" offers something (like that support) or if one guy does this when talking for a company ("we're now offering support"), even if it's free stuff.
While nobody would question the user to post his phone number and trying to help people unofficially on the phone, the company has to make sure the approval since it would deliver support for the product of another company (CS in this case).

Also, just from the objective view, the placement of "free" things together with a link where you can actually buy things (and not donate or something) is a commercial appearance (and therefore a completely different ballgame), even if friendly and surely talented guys like you post these things.
As nobody is allowed to place some kind of advertising here (apart from the signature which is a somehow passive element), this approval gets even more significant.

So don't get my thoughts wrong, they have a general intention, not the one to harm a nice guy.
