It’s not really an accusation, just that the trainer EULA expressly prohibits reverse engineering and/or merging the product with any other product. So both RXP and MS would need a special license from Garmin to distribute such a product on the Marketplace that waives these terms.
I’ve heard (but not seen) that RXP has such a license. Bur just speaking in general, that if not, that would be a barrier to any kind of Marketplace inclusion.
@CptLucky8 can probably shed more light on the Garmin license that they have procured.
