Please convince me that I should continue my support or advice what I can do. I’m prepared to do my part, but I can only do so if I can be sure that my support is not going to people who think arbitrary Censorship is alright (needs to be based on objective community rules and not on the political agenda of mods).
You do realize that the developers of Lemmy (the software) have a very close relationship with lemmy.ml, right?
My question simply relates to whether I can support the software development without supporting lemmy.ml.
No. You can’t support Lemmy without supporting lemmy.ml because the developers use lemmy.ml for testing. They have not created a means for users to separate out their donations from one or the other.
That’s why others are suggesting you should just support a different but similar fediverse project like PieFed or Mbin instead.
That’s not what your question says though. Your question asks for reasons why you should support the development of Lemmy because you don’t like the moderation decisions that the developers make on their instance. That’s a different question than “how can I support the software without supporting the people making it.” The answer to that is you can’t.
As others have said, you can fund your instance if you so choose. You can also try to fund a fork/replacement.
