I don’t think anyone should pay Apple to notarize their applications to be honest. It’s basically extortion that you need both a running $99 subscription and a MacBook of some sort to complete the process. I understand why big companies will do so, but for OSS projects it frankly should cost anything. I do wonder if the process would stick if companies like Google and Microsoft refused to do it though they obviously won’t.

That being said, I’m sure a lot of OSS projects are willing to accept it if you personally chose to pay the fee.
