It's of course true that software tends to get bloated when new features are added. Efficient optimization mitigates it to some degree as well as other design choices (just thinking how my wife's iPhone 5S works with just 1gb of RAM), however doing it requires time and resources, both which Jolla has lacked since from the beginning. It's balancing between time to delivery, features and money. Positive part is that now developer base for Sailfish is increasing. However, I have some reservations about the ownership of the company as I don't yet know how closely it's tied to Kremlin and how it might affect the development in the future.
