Re: paying the exFAT license "on demand." Yes, that would be the perfect solution. In fact, it really is the obvious solution, not just for Jolla, but for any manufacturer trying to deal with the M$ tax. The fact that it has never been done before leads me to believe that Microsoft would never go for it. It's a lot easier for Microsoft to force a given manufacturer to give in to their demands and provide a single lump sum payment, rather than trying to license each user individually.
