I tried getting away from Adobe, hmm, maybe three or four years ago. Mind you, I stayed on Windows because I'm too old to re-learn Linux but still - I'm totally with you. There are some alternatives and they're not bad but once you're used to Lightroom especially - gosh, it is just so very hard to get away from it. Photoshop, I could do with Affinity Photo but Lightroom - I tried, no way. I went back and am happily paying my Photographer's subscription.
