That's true, but teletext isn't theoretically more constrained than the Web is. There's nothing stopping, for instance, teletext operators from producing pixelated animations or scrolling text effects, just as there's nothing stopping Web developers from adding accessibility-hostile layouts.
In Britain, teletext hasn't been available for over ten years now, but at the same time, a department called the Government Digital Services do an excellent job of making public websites accessible - complete with ARIA labels, semantic elements, all of that sort of thing. I'd easily acknowledge that teletext was ahead of its time, but I don't lament its replacement with the Web.
