(Though replacing a smart thermostat with a mercury switch one is a five minute job if you're comfortable with it.)
At least in this case, ASUS routers all have local firmware install functionality, so this particular case is certainly not an example of engineers not knowing it’s possible to write offline updates.
Now if you’re really lamenting the lack of computing devices that cannot be updated remotely by design, that’s a different story, and might be on a ship that sailed a while back. The problem there is that local updates are inconvenient enough for most people that they aren’t done, which is problematic from support and security perspectives, even though there are legit problems with remote updates too…
Google no longer does search, it does "recommendation" and it sucks hard.

Have we all forgotten how Nest thermostats turned off the heat in the middle of January 2016 because of a botched software update? (Probably. It was hard to get Google to surface a link without a date due to so much SEO bullshit).
