The investigation by simo brought some results!
Exclusive interview with Juhani Lassila on the china connection

On the discussed Aigo:
"The similarity comes from factory design - smaller manufacturers save in expenses by selecting their design from an assortment offered by the factory. Jolla picked their hardware, colors, and of course added their unique software to differentiate for Finnish design."

And on taobao tablets with sailfish:
"Officially these devices do not support Jolla Store or updates, as they are not sold through official channels," says Lassila."

Now, this wants me to buy on of those chinese-sailfishs and try "OFFICIALLY not supported"!
Sounds like an invitation
