Making your own software is a good way to escape enshittification and influence.

I switched from Spotify to buying MP3s and using my own audio client, because I'm fed up of a company telling me which music I should listen to every single time I open the app. It costs more, but I own the music and I escape the constant redesigns, price increases and influential behaviour.

Most apps are very simple and there isn't too much to learn, especially if you're building it to scale to a userbase of yourself. I can't see the need for a ton of CRUD apps which demand subscription fees personally. If you build them yourself, you get to keep your own data, build it out the way you want it, keep it that way, and use computers as a person using a tool as opposed to a customer buying a product.
