“Colony collapses are a good thing” does not pass the smell test in any capacity and I would disregard that opinion without some significant evidence to back it up.

Yeah, it seems like a pretty naive zero-sum outlook on competition between native pollinators and European honeybee colonies maintained by beekeepers.

Colony collapse disorder of honeybee colonies, if caused by land use and pesticides and pollution and things like that, can be an indicator of the native pollinator population also hurting from the same causes, rather than some kind of opportunity for native species to get the upper hand in the competition.
