How do you feel about Venues that come and go with karaoke?

Here lately there has been a lot of venues like Fox n Hound, Ned's and Isleta Casino that have brought karaoke in for a while, then cut it. Then bring it back again, then cut. I see this as a bad thing for the community and for the venues that keep it going through thick and thin. Just like anything, in a years time karaoke has it's ups and downs, and it really sucks to everyone else when venue only does it at the peak. Should those venues be boycotted?
