Plenty of blu-rays thrive in the high seas.

If they stop making them its gonna be hard to rip them.

At least so far, some private groups have access to Widevine decryptors.

Widevine L3 are galore. Ahem

The problem is the quality.

Those streams are only like 6-10mbps bitrate. A regular blu-ray is closer to 30, and UHD can be well over 100mbps.

Depends, high quality UHD bitstreams from quality streaming providers are around 25 MB/s. That's ~50 AVC-equivalent.

UHD BluRays indeed go higher, usually 70-ish. But the former are already very watchable, and plenty of groups can get them.

Yarr

Yeah, as a physical media collector, this is pretty devastating.
