Keep in mind that maintainers of large projects are often burned or stressed out. On top of that, the "German" guy's first language is probably not English, it's German. You can't expect for every non-native speaker to always hit the "right" tone not because they are rude, but because they translate it from another language.

I think calling open source "greedy" is an antithesis and a sentiment that if repeated enough burns out the best maintainers. They do not work for the software's adopters and it is their fair right to ask for money if they spend time on doing work that only benefits others.

I recommend reading a bit about open source and expectation management: https://mikemcquaid.com/2018/03/19/open-source-maintainers-o...

In any case, it is unfortunate that the interaction did not meet your expectations. Keycloak is a great project, with a great community, and if it solves your needs you have made the correct choice!
