For example, 12 years ago W3C attempting to push "RAND" patent licensing into HTML:

This was 100% against the concept of a free, open web, and it took a huge effort to stop it happening. It's crazy that it even got that far.
So it's no surprise that they're pushing industry interests again today. I lost all confidence in that group safeguarding HTML a long time ago, and it looks like the they haven't changed.
