Wasn’t even aware it was still a thing, apart from on mobile (where it somewhat makes sense-ish)
Even on mobile my data cap only counts some of the time. Streaming services are not included.
So I can watch all of the YouTube or Netflix or Disney plus that I want and my data limit never goes anywhere. Basically it’s just for general browsing. Given that the bulk of my usage is streaming my data cap essentially doesn’t exist for me.
