The information you’re referring to is SOLELY about the Community Phone and not about the 10 IV or 10 V, to which completely different licensing terms may apply. For the Community Phone one has to pay Jolla an initial purchase price of 299 euros (which is way more than what that device normally costs on the market) so it quite possibily also covers the cost of software, whereas in case of 10 IV and V there obviously won’t be any such initial payment for Jolla, so the only income in case of those specific devices can be the monthly fee.
So maybe read more precisely what’s really written instead of scolding others, because the information concerning SOLELY the Community Phone has literally ZERO in common with how licensing terms for the 10 IV and V may look like.
