Its much more nuanced than that. Honey Bees are not native, but that does not technically make them invasive by most definitions. Oversaturation on a local ecosystem can push out native bees in some cases (maybe)...
As for the claim about them not being effective pollinators... Ive not come across anything that would make me believe that yet. In fact my understand was that its specifically because theyre good pollinators that they outcompete native species. Without additional information those two statements are incompatible.
They can spread diseases, but my understanding is that this is a result of the conditions the artificial colonies are kept in, not attributed to their inherent nature or biology, and might happen to any species that is subjected to those environments.
"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.
