RNIB in the uK are running a petition to try to put more regulation into video on demand services for accessibility, in particular Audio Description. I was listening to a podcast with the RNIB about it and they were also talking about screen reader support but not sure that's a focus.
It is totally crazy that some broadcasters (e.g. Sky and itv) crate audio descriptive content, but then it's not available on catch-up.
If anyone fancies signing it then here's the link: https://e-activist.com/page/102025/data/1?ea.tracking.id=web
There's a bit of blurb about it here: https://www.aop.org.uk/ot/industry/charity/2022/04/26/rnib-petition-calls-for-audio-descriptions-on-streaming-services
I'm not sure if you have to be UK resident or not, but the more signatures the better.
Sorry I know this isn't strictly speaking tvOS related, but I hope this is tenuously linked enough to not be considered too far off topic.
