Advertisers don't give a damn what advertising is "most relevant" to me. -> They certainly do, indirectly - that'd mean they get better ROI on their investment

Advertisers don't give a damn what advertising is "most relevant" to me. -> They certainly do, indirectly - that'd mean they get better ROI on their investment. But think of it this way. You are getting a service, you are paying either directly or indirectly through ads. Facebook wouldn't be a thing if it were a paid product from get go. It'd probably even lose a major part of its user base if it became a paid product overnight. Like i said, i would love if i can pay for a product i am benefiting from, but it's not always possible.
