Feel the same way. Honestly I think there's more money to be had going open source than competing in a sea full of sharks. But hey, that's probably wishful thinking from my part.
Nice files you got there. It would be a shame if they suddenly become unreadable, eh?
Even the so called "open" core is a joke. Just try to add anything useful. It will get rejected in favor of a paid option.
The whole thing is just an offensive anathema to open source.
