In the long term things are hard to predict. If we look from 2010, E2E encryption wasn't there, or atleast not in a form usable by the masses. E2E is now here, and is as easy as using Signal. However, you see countries making laws against it. I doubt they will let eSNI pass through. And eSNI will be much easier to block, since you don't need to block it for consumers, you just need to impose big fines on businesses using it, since any such business will need to earn money somehow from their customers in the country. Unlike E2E, you don't have to worry about some random person forking signal and running their own servers. And video on internet is expensive enough that only an entity with good bank balance can do it, thus easy to punish with economic fines.
