I don't think anyone has a problem with bottle episodes. It's the bottle episodes specifically starring Vic Fontaine which stretches the premise thin to incredulity that I think people--or at least I--have an issue with. Do another Ferengi or Klingon thing if need be. But attaching such sentiment to a character that the show really really wants you to like doesn't work for me. Again, he's a love him or hate him character. At least Ezri's episodes, while shoehorned, made sense for why they needed to be there if they had to have her as a replacement at all. Vic was just an insert the writers specficially wanted for no good reason.
