I'd guess that is the case for a non-trivial subset of the population.
And I mean I get ~15Mbps to my laptop when my connection gives me 50Mpbs, nowhere near something like gigabit which I'd guess is just an excuse for ISPs to fleece money out of people in all but a small minority of cases where people buy it.
But also I have zero incentive to upgrade my router because the internet is "fast enough" for everything I need, even with only using a small fraction of the available bandwidth.
Edit: Also to the headline of the article, my ISP doubled the base internet rate from 25Mpbs to 50Mpbs this year. So I guess the report lines up with my reality quite well.
