As someone who releases software under GPL and LGPL, and hardware designs under CC licenses, I don't see how anyone would sue you over a GPL license. Unless, of course, you took something from a GPL licensed software and then did not provide your users the same liberty you had with the source. Whether or not one individual prefers copyleft (viral) or non-copyleft licensing is largely due to their intent - not to garner the maximum number of users, but to ensure that anyone else who might profit from their works affords their users the same right. And, if you really wanted to people to do whatever they pleased with your work without regards to your desire, you would've made it public domain, not MIT-licensed. You chose a license because you had a desire that the license enforced.
