>Ads are a donation box, not a price tag

Well, you're certainly entitled to your own opinion. But realistically, we all consume content that is ad-supported that we might be paying for otherwise. The fact that so many ad-or-pay services exist is proof of this (Youtube with ads, Hulu with ads, etc.) The are both business models.

If you don't like the service at the price, don't buy it. Honestly, no one is forcing you and tons of people get on perfectly fine without Facebook (some people would even say they are better off without it).

You say "buy" but I do not see how this applies to Facebook. I do not buy anything, there is no money changing hands, no product offered or received.

But ads isn't real donation, no actual money is handled from customer directly to the website. Instead, advertiser pays for it.
