I did not mean to insinuate that playing multiplayer between Java and Bedrock was possible at some point. I mean to say that playing multiplayer "Minecraft" between Linux, Windows and macOS was possible, but is no longer possible, since "Minecraft" is now a product which doesn't work on Linux and macOS.

If you don't see how what I described could be characterized as "hostile", you've either misunderstood something, or we have a different understanding of what "hostile" means.
