Unpopular opinion but the CC text on is pretty addictive. Complete dialog includes background music names of songs and lyrics. It also reveals those mystery moments when someone talking is not in frame. For crappy actors who mess their lines up you read what they intended to say and the scene is more complete.

Next it will be narrators in movie theaters so blind (oh, sorry 'vision impaired') people can be included, too.

In the tech world, the ADA people and their bullshit are almost worse than the "Diversity" HR people.

CC is usually reserved for recorded shit, sign language is usually reserved for live events such as press conferences
