I can only assume you’ve never worked in desktop support if you think that is something the general populace is remotely interested in. Smartphones are a step in the right direction for the tech illiterate and uninterested. There is zero reason to give lay users enough rope to hang themselves with despite that being the opposite of what I or most users of this site would like for ourselves.

Also the number of times I want my speaker or TV to go online is zero, while Samsung apparently wants that number to be greater than zero for both products. So it is frequently the companies that put us in this situation in the first place.

I would assume your browser automatically applies security updates in the case of 0day exploits, no?

Like I said, automatic updates are an evil. But the general populace will absolutely defer every security update until the end of time so long as they don't have to spend five minutes waiting to get to their desktop.

Obviously vendors enshitify their products via firmware updates and potentially brick devices or introduce new vulnerabilities but, it's ludicrous to pretend that the general populace are good stewards of their internet connected devices or that they ever will be. They simply do not care, they never will, and its up to the rest of us to design products for the lowest common denominator if we want protect end users and have a safer internet.
