Ask HN: What accounts for the update-happy nature of modern tech?

I struggle to think of an internet-connected device that I own which has not required an update in the last month. My phone (Android), my computer (Surface with Windows 10), my game console (Playstation 4), my tablet (iPad), my /light bulbs/ (Philips Hue), all needed to be temporarily bricked and to install either a security or feature update, generally without seeking my permission to do so. Also, essentially every major app on my phone. I know HN is frequented by people from across the range of specialties within hardware and software development; I'd like to hear everyone's take on why this has come to be the paradigm, and their sentiments on the matter.
