Having read the article, I guess the change is not so much a matter of "leaving the Amiga" (though there is a hint of setting it firmly into a "retro" context), as expanding it into an "alternative platform" Rumour Mill.
If this is what will happen, I guess I'll still hang around and read it for a while. However, if the focus shifts mostly on MacOS, then I will certainly lose interest. Nor because I think MacOS particularly bad, but because I am extremely unlikely to ever own a computer running it, so I'm not going to spend too much of my time reading about it.
