If you want to continue to use Strawberry, you could stream your music with a subsonic server, Strawberry supports that.
For me it was the other way round: I was using Nextcloud music and searched for a music player on Linux that could stream my .flac-collection via subsonic. That is how I found Strawberry.
There could be 3 out of 1000 people that make you feel not welcome. Don’t judge a platform because of those 3 people. Maybe it helps to focus on the 4 out of 1000 people that make you feel welcome. And don’t think about the 993 people who really don’t care what you write.
