Due to the way apple restricts development on their platform, one has to recompile/reinstall homebrew software every 7 days for it to work, effectively killing FOSS development for people who don't own the bundle/app IDs. I once paid a 100$ to try and contribute support for NFC for an open source app, only to not be able to use my functionality without upstreaming it. Judging from this experience alone, it feels like Apple hates FOSS.
The point isn’t that it’s easy to do but that it’s fully doable for someone that doesn’t want to contribute the $20/year to development of the software.
