i remembered when they told me it was possible to stream "HD" (i assume 1080p and not the "fake" 720p) at 1Mbps...
that seems to be impossible now with the all encryption, ads, trackers and UI bloat on Youtubez and other streaming media sites. that and they probably use a lot of uncompressed audio or lossless audio formats on streams now.
Facebook seems to be the worst offender. even with adblock, their videos (at lower res like 540p) would eat up all my RAM and sometimes hang my laptop.
their non-javascript video links seem to work fine though. so does Instagram videos, which is now owned by ZUCC the Facebook lizardman too.
