Well, all I can really think after reading this is “fuck apple”. I’m getting very very tired of their walled off closed shit where they even try to make life as hard as possible for people who try to support it despite the odds. This isn’t the first time either, it happened to VLC before.
Did we read the same article? Seems like Apple has been happy for this guy to have a signing certificate for his kernel extension for years. And he has been using it, and everything has been fine. Now the guy decides (not unreasonably, IMO, though it clearly impacts a lot of people who're used to getting the benefit of his efforts for free) that he wants to make some money... and the conclusion is "fuck Apple"?
Also, my complaint is mostly that apple keeps changing their API’s, as you can also read in the article.
All together this kind of stuff makes life needlessly hard on third party developers, so yeah, fuck apple.
