Having data means nothing if you can’t monetize it.
As you say, AI can already access it all completely for free with nothing more complicated than a web crawler. Long term, charging AI firms for access is not a viable strategy unless the law changes.
And they’ve been trying for years to monetize visitors through advertising and other schemes, and so far come up consistently short.
A small set-top box (essentially a Steam Deck with the screen, controls and batteries removed, and with components that don’t have the space restrictions that come with a mobile device) would still be an interesting proposition. Particularly if they partnered with the main video streaming services to port their apps across, and implemented Chromecast/AirPlay support.
I can see a market for it, as a “Chromecast and Apple TV competitor that also plays all your games”.
