The most they'd do with this is allow roll20/FG to build tools to move data directly from Beyond to their platform - at a price.I think in an ideal world, yes.
This is part of why I think it might be worth them buying Beyond, unless it's unreasonably priced by its current owners. If they bought it, they could simply keep it going, and just keep the userbase. It's not like anyone is using it because it's not WotC. Quite the contrary.
I don't think you could "grandfather" FG/Roll 20 people across, realistically, because they're competitors. I mean, technically you could give people codes to transfer over but to do that properly you'd need FG/Roll 20 to collaborate with you taking their customers, which I think is unlikely. What is also possible of course if that you could buy Beyond, and make it the "direct pipeline" to your material whilst letting FG/Roll 20 exist as sort of "lesser" versions, but given the way WotC operate I'd be slightly surprised if they went with that.
Unless they plan on building their own VTT, in which case of course they'd work against sharing data with other VTTs. But I for one haven't seen any direct indication of that for WotC.
