RentMount.com - would listing with them cause problems with Google Vacation Rentals?

I received an email from Mount asking if I'd like to list our property on their site. This is from their email:

Here’s what we’re hoping to do: connect our travelers directly with hosts like you—no third parties, no middlemen. We want to make it easy for them to book directly with you, bypassing the traditional channels, while you gain access to quality guests. In return, we’re simply asking if you’d be willing to offer our community a special discount. Think 5-10% off or an additional night if they book a certain number of days.

But it seems to me that this would create inconsistent pricing and therefore get in trouble with GVR. Am I correct?

It looks like RentMount has already integrated with some channel managers, you could certainly suggest that RentMount write to OwnerRez's open API so they can be integrated here, too.

GVR has no say about your connecting to other channels. If you choose to give a discount on RentMount, that won't affect GVR, just as your pricing on Airbnb & Vrbo does not need to match GVR. For Google, it is about your website pricing.

Until they API connect, you may be able to iCal connect to RentMount; that means setting up your listing and pricing manually on their site.
