It's fine to relax with such logical confidence, but it still all depends on the decisions of companies. Fear of things vanishing is warranted due to many recent happenings, even if extraneous. I'm unclear whether NSP recovered from that recent delisting of PSP patches (can't find the discussion) And of course the DSIware that you alluded to that mostly returned, very scary to see this. Other platforms are also in transition, the Oculus platform (gear vr, rift, etc) is about to lock out Oculus accounts entirely, forcing facebook login for new devices. And Facebook has NOT made it clear that current users can still access things without the login.
