Since the Internet is not as widespread in Mexico, I'm pretty sure most of the population have somewhat different priorities.
Even Mexico's own numbers (by AMIPCI) show Internet usage at 27.2% of the population vs the US's 77%. This is even lower than the ITU's estimate of 43.5% penetration for Albania.
How many Albanias do feet inside Mexico City alone?
Also, I think this was a good decision from the Senate. The country has made some serious strides towards true Freedom of Speech during the last decade.
