I just got an email regarding this issue, this is crazy.
You guys clearly stated forever, and now you're saying that different CPU Architectures and Different Operating Systems require different methods of payment?
I'm sorry, and with all due respect, it's not our fault the wording was wrong. You told everyone that they'll be getting SVP Free Forever. This means ANY Final Version of SVP will be free to those who paid $10. And ANY Beta version for those who paid $100 or more (regardless of Operating System).
Personally I paid $25, personally I'm happy as long as I get SVP Free for Windows forever, but if someone uses both Windows + MAC + Linux, I would assume they would be fuming (pissed off) right now at this news. I too like Nintendo Maniac 64 will stand for the principle, this is WRONG! You guys exceeded your expectations and I am happy that you guys exceeded what you set out to do at the start, which is get $5000 to $7000.
But, and I'm sorry if this sounds wrong, it's starting to look like you are milking it now.
I recommend that you guys register every email that has donated SO FAR, so all the people that have already donated $10, $25, and $100 will get every version for free, but from NOW ON, and because you added the wording now into the Indiegogo website, will have to comply with the NEW rules. Meaning they shouldn't expect the Mac and Linux versions to be free from NOW ON. But all those who paid before should, because you didn't specify that they should not.
