No, not really. Xiaomi gets feedback from their customers. Jolla does not have a product yet,
Btw, stalking them on twitter is not constructive feedback. Let them just finish their product, they have no obligation whatsoever to give out further product specs or details about their plans. When they do it's great, if not, don't harass them, it just keeps them away from more important things, like coding or, probably, sleep.
