It is. This is just several more steps up the atrocity ladder. Web site weight has majorly outpaced the growth of the average internet connection speed, and we also live in a world where mobile usage is up and many people have usage caps.
I pay per gigabyte with a prepaid plan for my phone, because I'm not paying $40/month for phone service when I can pay less than half that, so blindly clicking a web page and having 20MB quickly used up sucks.
I hear ya. I find the "unlimited data" plans are just far too expensive to justify paying for. My current carrier (Verizon[0]) offers 4(!) different "unlimited" plans starting at $70/mo and going up from there. My Wife and I only have 2GB/mo plans which itself is $35/mo. Our two cellphones have a higher bill than our entire household electric/gas bill and we have a modest sized house with central air/heating and lots of TVs/games/etc.
