I see what you are saying, but I still think it is a far cry from having content providers simply providing the feeds themselves.
In the same way that I don't think that YouTube allowing users to submit closed caption transcripts, or machine generating them, any substitute for the content creator
providing them in the first place. I'm sure in the near future, smart TVs will be able to machine generate closed captions from the audio, but I still don't think we should let television producers off the hook for providing captions.
RSS should be the default. And it is not hard to generate RSS.
I happen to think that big platforms only reluctantly adopted RSS over a decade ago because it was a "standard", and because they felt that it was popular enough to justify the traffic from it. But they do not like RSS. It works against their analytics, their ads, and their control of the presentation.
And while it is cool that people are crowd sourcing scrapers, I think the real solution is to promote RSS itself and encourage more platforms to simply provide it. And organizations like Mozilla taking Facebook's position that RSS is obsolete has been profoundly unhelpful to the web.
It's not an outlandish amount of work, if lots of people chip in with their favorite source.
