Y'know, unless I want to participate in community events in my town, which seem to only use Facebook these days.

Or find out the hours of a local business, which only has a Facebook page (or worse, instagram!) and no website at all.

Or use a phone or tablet that can connect to the internet -- turns out both of the companies that make 99%+ of smartphones have advertising businesses. And nobody makes apps for any other platform, so they aren't viable.

It's a lot like riding public transit, or using public highways, all of which are plastered with ads in the vast majority of the US. These are things you really can't avoid, so the advertising has essentially become mandatory.
