The way I see it, we should basically answer ourselves one question: Do we gain anything from offering Inkscape in the Windows store that would make it worth our while?
As Mc I'm strongly opposed to putting any price tag on Inkscape. Doing so would be the right approach if we wanted to handicap/penalize the Windows store on purpose (I know this from a few open source applications available from Google store for a fee while they're for free otherwise), but in that case I wouldn't bother putting Inkscape into the Windows store to start with.
Donations are obviously fine, but I don't think that such a discussion would be specific to the Windows store.

P.S. (Off topic but I have to mention it - maybe worth a second thread, though):
To all of you who seem to have dollars in your eyes: Does anybody of you have the impression that the speed of Inkscape's development is currently limited by money? Is any of the active developers paid? Would any of the active developers would want to be paid in order to invest more (spare) time into Inkscape? Where should this time come from? I honestly don't have the impression we have a reasonable idea on how to invest any potential money/donations that would be earned/raised in order to actually benefit feature development. (The one thing I see where money really is advantageous are hackfests. But then again one was just canceled because of lack of interest/time and I doubt money would have change much about that...)
