Where did you get that from? Any secret sources? (It might have been of course, but that's either some secret information from Jolla - or speculation.)

I'd say that's highly unlikely because the total cost of the tablet project was much higher than the amount of money raised via IGG.

So it was like: In the end, they had 2 bathtubs filled with coins. That's what the project cost them.

The money from IGG was enough to fill the first tub. For the second tub, they had to use coins for their own pockets (or rather, their inverstors').

So at which point would money from IGG have been mixed up with other business? (Which business, btw? They don't own a bakery or such.) Even if one of the IGG coins for some reason ended up in Jolla's general budget, that's exactly the budget they used for filling up the second tub.
