He's not entirely wrong...
In real terms, I kinda see his point.
I've upgraded my internet from dial-up to 1meg "broadband" and now I'm all the way up to a lovely "200 meg" connection. I can get the full bandwidth, Speedtest proves it.
But, in reality, my downloads haven't got much faster since I upgraded from 50 meg. Despite their being sufficient bandwidth from the source (especially P2P swarms) it just won't go any quicker due to traffic management algorhythms in place.
Meanwhile, stuff like Speedtest, Netflix etc. have indeed "speeded up" with the speed of my internet connection.
So I'm using the same wire and the same modem, the ISP has speeded some stuff up, but what I actually use it for hasn't seen any significant increase.
The only real use for a fat domestic broadband pipe is for multiple concurrent streams, like 4k Netflix in different rooms - achieving the full bandwidth is nigh on impossible.
