@wolftune @lightweight @snowdrift Well, but it's not the same websites though: toyota.com buys ads and pays them with revenue from car sales, while, say, lwn.net and phoronix.com use the ads income to finance daily Linux news.
Both these sites also ask users to subscribe (which I do), but won't you agree that they might have to scale down their operations if they were forced to survive solely on subscription revenue?
