OK, Different angle, here . . .
Official Xperia 1 or Xperia 5 series support with VOLTE would solve the hardware portion of North American usage – the Xperia 10 series lacks many/most of the 4G bands needed here – presumably removing that issue from the list of whatevers preventing sale in the US/Canada/etc. My uninformed WAG is that the rest of the whatevers are license-negotiation things, but if that could be worked out North American sales would open several new markets.
I’d love to be able to recommend SFOS to friends and family if they didn’t have to visit a Sailfish country (in person or virtually) to buy a license and network coverage was much better. With the 10-series, it’s just pure luck if your phone works where you need it to. I love Sailfish, but I get grief from my wife if I’m not 100% available
