The further you get in physical/geopolitical distance from the US the more you invalidate assumptions that many US sites and services make.
I've had sites fail because my local time can be one calendar day _ahead_ of theirs... and how could you be doing something in the future?
Once you get into regions with a combination of censorship on the foreign-side and aggressive 'security' measures on the US-side (blocking/triggering on IP ranges of entire countries, VPN services, could services, etc... 'cause why would a legit user be coming in through anything like that, right?) then it really gets rough.
Generally, to reliably serve a country/region it requires specific expertise, personnel and/or infrastructure.
And BTW when I priced out a "reliable" connection in Beijing years ago it was around $1K USD/mo for 10Mb. Not exactly peanuts.
You severely misunderstand the realities of international students. You're making sweeping generalization about a lot of people you know nothing about.
Fyi, There are parts of the world where money can't buy you steady electricity, safety at home (an especially important point for women and LGBT), reliable internet access.
