Given that Microsoft and Apple take a cut of all sales through their stores, it seems it would be a strong encouragement to buy direct from Serif if they would offer cross-platform licensing as a perk. They wouldn't have to increase prices to generate extra revenue - it wouldn't be as much as two full licenses, but it would be more than via somebody else's app store. Having to buy a separate license for my third-string device (a Surface Go that will only really see much use when I'm able to start traveling again) feels a bit archaic. Yes, it's currently only $25, but I'm deciding what to pick up before the discount ends - I already own Designer for Mac and Designer and Photo for iPad, so do I get Photo and Publisher for Mac? Photo for Mac and Windows? I'm a fairly happy Creative Cloud Photo Plan subscriber, so these wouldn't replace those apps for me, but I'd like to support Serif for being generous at a difficult time.
