Here's my two cents:
OK, so people moan about the sponsor and accuse you of stealing code.
But look at it this way: how many of the 6,000,000+ users actually moan? From what I've seen, far less than 0.1%.
I wouldn't have over 1000 posts on this forum, and written nine plugins if I didn't think Plus is worth the binary it's distributed in.
People will always complain about things they don't understand. The true worth of a person can be (partially) measured by how they deal with lack of understanding: those who refuse to research a little and just fly off the handle aren't worth the air they breathe (or the ASCII they write), whereas the good souls in this forum, who do research and come to straight and honest conclusions, are worth their weight in gold.
Keep working on Plus, for the sake of humanity!
