For instance, I see no reason why a password manager should be a SaaS. I don't care how long these companies have been around thusfar; in my opinion, using a password manager as-a-service is asking for trouble and is a waste of money. The closer you approach "perfect" security, the more of your personal security you end up handing off to someone else for their profit. Having a handful of sufficiently complex yet memorable passwords and something like Authenticator or Yubikey might be an appropriate compromise.
Image editor? There's Kirta, GIMP, and Inkscape. No, they're not as good as Adobe software, but maybe that's less important to you than not paying Adobe.
Maybe just using Apple Notes can be good enough for you, if you can get used to it. No subscription necessary. Back it up on occasion. There are of course other note taking apps that aren't SaaS.
Too many streaming services? Consider watching less in general. The less you live vicariously through fictional characters, the less those fictional worlds will matter to you. Spend that extra time learning a skill or spending non-screen time with others. Not watching television only seems abnormal in the context of the last half century.
Tired of "live service" games? There's a million older games that you buy once, probably for way cheaper, and don't have a ton of bugs. Nothing is wrong with older games.
Subscriptions are mostly a problem for those with FOMO. Don't care so much about living in the now. Create some distance between you and the technological machine while still being able to interact with it when you think it's sensible. The only way that companies will back off from everything being a subscription is if enough people who don't appreciate it actually take action in their own lives.
