I'm not offended, it's a debate

, in a debate you get to hear all sides whther you like it or not!. The "VB Team" you are talking about aka Zachery and Lynne are both prolific coders in their own right and as they have given so much to the community both in coding and support help to non mod questions they've joined the vbulletin team.
As Zachery said he marks ALL his mods unsupported but supports every one of them, just think about all the great stuff you'd miss if you only ever went to the "supported mods" forum!
If you truly wanted something supported you'd have to go to the paid section of these forums, again you'd miss out on great stuff.
