While it's unlikely that they won't attempt to get something similar to WEI onto the internet at some point, they have recently given up on this iteration of the concept.
I agree with you that such efforts are always a threat, and I'm reminded both of the V-Chip and the current efforts in the UK to keep blokes from watching their porn (anonymously, that is, without ending up on a registry of porn watchers), what may end up adding the right to porn access as a specific chartered right in our universal charters (and some national / state charters). Here in California, the right to produce porn is explicitly established in state law, which is embarrassing to some, a point of pride to others.
The MPAA and RIAA also tried to get all the ISPs to agree to shut down (or throttle) service after twelve strikes by an anti-piracy board, who would track the IP addies of torrents. This fueled the development of magnet links (now the standard). And meant that Xfinity and AT&T had to be extra shitty to customers due to causes they don't care about, while folks are already desperate to disconnect from them in favor of an alternative. So they haven't really be enforcing it.
And yes, Google is retreating on the WEI thing for now (if only they could get the federal government to pass a law) but the blowback on an eventual universal DRM is going to be severe, including revealing to the world that TPMs don't do what they are supposed to do as explained to the end-user, making them hostile architecture. It'll also potentially send increased traffic (and increased business) into the EU, or out of the US into less traceable regions, and get the determined end-user interested in the dark net, because watching a cat video without ads now requires the same savvy as getting access to CSAM, active revolutionary news and restricted chemistry configurations.
What will be more interesting to me are the consequences I haven't imagined. To quote a favorite princess, The more you tighten your grip, Tarkin, the more star systems will slip through your fingers.
Anyway, the go ahead and downvote me line is creepy, and brushes against poisoning the well I don't downvote dissenting opinions, (and can't, anyway from my Lemmy instance).
