Note that AGPL does not actually protect your software from big companies (or small companies) running your software as a service. It requires them to contribute back or make source available when they make changes, and IIRC thats
to the user (who could be an enterprise customer under some other agreement even, but none of this is tested in court).
If you want that sort of protection, BSL, SSPL, Elastic license, etc are what you want.
If you want to make Free Software, make it. Know that people you don’t like may use your software, even criminals may. That is what Free Software is. OSS is slightly different but similar.
If you want to make shareware, make shareware — no judgements on people who want to make money with their software and believe thats the best path.
