Ironically, 8-10 years ago my carrier's cellular network felt so fast that a young, naive version of myself expected to never sign up for broadband internet. I used to actually play video games on this connection because it was way more reliable than my home internet connection. But in the past 4-5 years, this same cellular network has become a high jitter, low bandwidth disaster, despite "upgrades" from 4G LTE (i.e. faux 4G) to what my carrier claims is "5G".

I'm aware this is just an anecdote and n = 1 implies infinite variance and what not, but it's amazing seeing countless people have such a good cellular network they can just ditch broadband subscriptions.
