I recall reading that despite the internet being faster, actual website performance has never really improved meaningfully. Whatever speed gains we've achieved have simply been eaten by larger and more complex tracking scripts.
Google themselves are a significant contributor to this problem, for many websites, Google's scripts are the core source of slowness.
I don't think it's unreasonable for users to want to reclaim their browsing experience (and bandwidth). In the sample comparison below we can see savings as high as 90% of data and speed boosts of ~1500% - it's insanity.
