My main problem with Adobe is that it doesn’t work on Linux, and I’m not going to do some dual-boot stuff with an OS that works like hell just to use a software with worse stability than FOSS ones. I hate Adobe mostly for the lack of stability and Linux support.
You can use other init systems on Gentoo, like OpenRC. You can also use other distros like Void(which uses Runit as PID 1), or Artix, which can use OpenRC, Runit, s6 and dinit. Most of those are much better option than systemd, however, you can have compatibility issues with some packages that relay on systemd.
Oh, okay, I misunderstood you.
