R2's new equity investment partners have every incentive to try to maximize their returns by using exclusive licenses to protect their sales. They are not in the hobby/model business, they are in the making money business. And if you can make more money by boxing out the competition (like Revell tried and failed to do to Bandai) then they will try it. Of course they will. They answer to their investors. I'd love to believe in the virtues of the "free market," but if you think R2's new owners aren't going to try to create a playing field where they 'compete' by being the only team on the field then I have some Gamestop stock to sell you.
According to a Facebook post from Revell many moons ago, they had nothing to do with shutting down Bandai.
Either Disney enforced it, or speculation is that Hasbro spearheaded it
It did happen right around the same time Hasbro forcibly acquired/shut down the Fantasy Flight Games Imperial Assault game because they considered it to fall into the board game category, not the table top miniature game. In addition Bandai was allowed to distribute through BlueFin, but if you remember, they initially could not import the figure kits as well as removing the 3D figures from the vehicle kits. Again speculation being that it was on the basis of having too much competition for the Black Series and possibly even the MicroMachine series (which was close in size to the vehicle figures)
Regardless of who may or may not have complained to Disney, it ultimately was Disney draconian licensing that cause the issues
It is also up to Disney to decide to whether to grant an exclusive license if there is one to be had, not Round 2
Remember, while Revell USA was producing/releasing Star Wars kits, BlueFin was still able to import Bandai vehicle kits and eventually extended that license to the figure model kits, although I think that may have been a more limited list. For example, I am not sure if they ever were able to import the SpeederBike or the STAP among a few others
So unless Disney has renegotiated the terms of the Bandai/BlueFin license, they should still be able to import (at least for now)
When that license renews however may be a different story. For all we know it may have already been done.
Unfortunately with lack of any press releases from BlueFin or Bandai we have to wait and see how long US retailers are able to restock Bandai kits through BlueFin
