I was intentionally equating them to emphasize the problem. If you're not educated to discern the difference between traditional education and advertisement, then there is no practical difference.

Coca-Cola (and advertisements for it) is more widely available than basic education. I personally think this is unethical on part of the advertiser, doubly so when you're selling something that's both unhealthy and somewhat addicting. There are populations in the world who can't read, but can recognize the Coca-Cola logo.
