I know of no alternative that isn't infected with Jєω/Masonic propaganda.  There are obviously individual videos out there, but they're not really gathered in any one place.  So if she's watching a lot every night, the sheer volume can't be kept up with by any alternatives.  If she doesn't read due to eyesight challenges, then there are lots of audio books out there as well.  But you'd probably have to go to the trouble of creating playlists for her somehow, both of videos and of audio books, etc.

Perhaps you could take on the effort of creating a website with categorized links of decent videos ... where the links could be to Jєωtube or any of the alternative streaming services, and also to audio books.  That might be a good service to provide.  Start collecting and categorizing (cataloguing) links to various good/decent videos about various subjects, and gather them in a single location.

That was me above.

The Margarets are numerous, from Margaret Bosco to Margaret the Virgin and Margaret the Englishwoman. Then there are the Margaretas and Margaritas too.

Instead of TV try silence, to whatever degree possible. Most of the time the TV looks better turned off.
