I had replied to a different thread but I think it’s worth linking here:
To answer the topic question directly, I’d say we are
mostly FOSS but pragmatically.
If someone posts a Ps edit but is engaging, answering questions, and responsive then it may still be a great thing (after all, we are also photographers here). We can still learn neat things in the context of FOSS hopefully.
New users dumping Ps edits and not responding to questions == bad.
Users posting Ps edits and talking about the creative process, the technical steps to get their results, and why/how they accomplished their results == good. Then we can have a discussion and possibly share results using FOSS tooling that might help them reconsider their choices or options.
