I updated a Phillips (I think?) TV - years ago, so this was over-the-air, not internet - and the built-in Program Schedule started showing adverts that were obviously in the update.
Eventually the ads stopped appearing, so at least there was some form of expiry date, but no, I’m very wary of consumer updates.
TVs should remain as display devices. I even keep the tuner equipment as a separate device to upgrade separately - sorry if that doesn’t increase their market share.
What next? A toaster with butter spreader built-in?
🤔 interesting idea…
