... If there were an ever-evolving landscape of awful things crawling up out of my sewer through my toilet, I would very much want to pay for automated toilet updates to prevent the most recent awful crawling horror from appearing in my bathroom.
If the people who produced toilets ACTUALLY cared about stopping the ever-evolving landscape of awful things, they could:
A. Release security updates independently from feature updates
B. Stop adding random features that hook you up to more unwanted landscapes, or landscapes at all (software that could run entirely locally without network access but have network access anyway, updates that force ads, the updater itself, etc.)
but they don't because that's not the actual reason they have automatic updates.
