This would explain the response I got (backstory - I am a contributor to a number of open source packages / not totally clueless, but was coming in from a micro personal account). I was like, how the heck do they afford this response for $99! (or whatever it cost back then - this was a long time ago).
I kept my support plan active for a year as a courtesy though I never had another question aside from the first two I put in.
That said, as a programmer I like time to focus so being asked customer questions would drive me nuts, hopefully they filter out the idiots who just can't setup things right (80% of issues are not bugs but customer setup issues).
