Dialup became useless long ago because of web bloat. My mom had a rural dialup connection that typically managed about 30kbps. 15+ years ago this was enough to load Facebook, Gmail (even without its fallback basic html mode which is gone now anyway) and so on. You just had to be patient the first time while all the graphic assets got cached. Some years later she was on a cell network connection with 128kbps fallback…
The worst part was how little actual content actually makes up the bloat. Sure video was right out, but I was often struggling to load pages that were mostly text.
The only other option at the time was Hugesnet. After doing the math I determined the data caps were so low dialup was actually cheaper at MBs/month and had less latency issues. Realistically the next best available step up wasn't Hughesnet it was shotgunned 56K.
