Wholeheartedly agreed!
It is also nice to have that additional assurance of being able to self-host things (if ever necessary) and not being locked into a singular implementation. For example, that's why managed database offerings generally aren't that risky to use, given that they're built on already established projects (e.g. compatible with MySQL/MariaDB/PostgreSQL).

MinIO is pretty good, but licensing wise could become problematic if you don't work on something open source but ever want to run it in prod. Not really what this discussion is about, but AGPL is worth mentioning: https://github.com/minio/minio/blob/master/LICENSE
That said, thankfully S3 is so common that we have alternatives even to MinIO available, like Zenko https://www.zenko.io/ which is good for both local development as well as hosting in whatever environments necessary. I was actually about to mention Garage as well which seems better because it's a single executable but they also switched to AGPL, probably not an issue for local testing though: https://garagehq.deuxfleurs.fr/
