If you refer to the first part of "thanks to the internet": for basic BDs, keys to decrypt are available up to the end of 2019 (depends on the release profile).

If you refer to the first part of "thanks to the internet": for basic BDs, keys to decrypt are available up to the end of 2019 (depends on the release profile). For newer/4k movies, these keys are not supposed to be used offline and as such have to be checked out (with your client verified) online... As for your latter part: yes, I guess that's the aim, but piracy generally works just fine for streaming. And as long as China is not the cultural hegemon, some way to grab the bytes off the transport will be available.
