Rant!
Got an email from an extension developer who releases code under GPL. Had a list of all sites using "our copy" of his software and demanding that we pay twice as much now for download access. We've only asked for support on one domain ever so this feels like an underhanded way to treat customers when your software is supposed to be GPL.

Absolutely need his product so we paid it. Feeling very annoyed that GPL software license isn't really being honored. And it's creepy that he's tracking it that way.
