I wouldn't be surprised if your experience hadn't changed: Net neutrality rules were gutted at the same time as the internet has been largely consolidated, so major players paying for "fast lanes" and the ISPs throttling other kinds of traffic is, statistically, likely to have gone mostly unnoticed by you as an end user. If you have internet use cases beyond that which is endorsed by corporate tech, you will likely have noticed a stark difference. I've found that things like SSH tunnels have been less reliable, that there is noticeable slowdown when I find myself on a smaller website (Like those maintained by a shrinking minority of local vendors and artists who don't do everything on instagram). The most obnoxious thing about shady degradations of infrastructure in the name of profit is that these changes are often made in a way that's hard to specifically pinpoint, and by entities that make it somewhere between infuriating and futile to address any kind of complaint to.
