Unfortunately, the W3C web accessibility initiative hasn't taken that 
position for many years, and as most legislation that is prescriptive on 
standards uses their web content accessibility guide, EcmaScript 
dependent pages are generally fully legal.

(My take on this is that WCAG membership is mainly accessibility 
consultants, and consultants need solutions that are acceptable to 
businesses, or they will be out of business themselves.)

I actually note the OP wanted an accessible way of using YouTube.  I 
think Alphabet's lawyers will have convinced themselves that the 
standard web page is legally accessible.

Also, the intent of these links is, as I understand it, that no HTML 
fetch should actually happen, but rather that the loaded EcmaScript 
should generate a new document object model resulting in a changed page 
layout.  Although the fallback might be fully functional, if I wanted to 
do that I would use a straightforward URI, and have the scripting 
intercept it.  I'd therefore expect the fallback page, in many cases, to 
only be suitable for use by Google's search engine.
