My expectation is that most backers are interested in open technology. It doesn't mean they are necessarily tech savvy. And such people wouldn't appreciate sending their funds to an entity like MS and perpetuating exFAT lock-in. It's not really about tech savviness, but about why would people support Jolla's campaign rather than going and buying any of the tablets which are already on the market? I see it as voting with your wallet, and as such funding MS is like negating that vote.

Of course I may be wrong and people just fund for whatever other reasons. I'm just expressing what I expect.
