My understanding is basically that DRM is the technology that permits the existence of Netflix and similar. Perhaps I just lack a strength of principle, but I don't see why you'd remove one of the most-enjoyed aspects of the internet for the sake of uh... some kind of privacy-adjacent something?
We got to an ok compromise of video tags and native browser support, with DRM extension for corporate needs/reqs... Is it the best? No. Could it worse, definitely.
But without it youd need a Netflix app on your PC... And what safeguards does that have from hoovering my pc usage up for sale or marketing? Atleast Netflix only gets MY Netflix consumption for their metrics and ML, and isn't cross referencing the games I play or other things I'm doing at the same time.
In addition to the privacy concerns with native applications, they're almost always insecure. One thing that is nice about modern browsers is that (despite Safari's leisurely update cycle) they are actually relatively secure, as far as software goes. Threats to the average user of Chrome are things like phishing, rather than RCE, and tab isolation keeps things from escalating out of control.
Contrast that to the now ubiquitous conferencing software solutions, and it seems like every day there's some zero-day RCE vulnerability or other spooky exploit.
If we needed to install and run a dozen different closed-source executables from BigCorp et al., I predict that we'd very soon go back to security dark-ages.
Netflix make money from their subscription service not DRM. I can easily torrent anything I watch on netflix but I watch it on netflix because its easier. Thats why I pay for netflix its not because their DRM prevents me from pirating anything.
