I've got to admit that I'm constantly fascinated by how much fandom certain entertainment groups get at WDW. I have nothing against the likes of MS&S or Off Kilter, etc and would be entertained enough if I came upon them and they were playing. And I get that some people are more or less interested in certain types of entertainment.
But these are cover bands. They don't -- as far as I can tell -- do anything particularly special that hundreds, if not thousands, of bands do every day throughout the US. The location being in WDW might be neat, but they seem pretty replaceable to me. I just don't get the woe that occurs when certain entertainment is replaced and I certainly don't think Disney is evil for changing the entertainment periodically -- heck, they should probably do it more frequently.
I'm 100% behind the point of disliking when entertainment is cut without a replacement. We'll see what happens here with DHS, though I've got to think some sort of replacement will occur given the state of the park. Disney should be criticized for decreasing overall entertainment offerings when it occurs. But I just can't get worked up over any individual act being gone. YMMV.
