I'm anti-ads because the kind of ads that I am being exposed to are invasive, especially re-targeting ads. I.e. those ads where you've been on a website and thought about buying something, then decided against it? Then you get the same product advertised to you on random other sites you visit.

I cannot stand it when those ads follow me around. In fact, assuming I didn't buy the product or service for a good reason, and I do want to buy the product, I will deliberately buy from a competitor, because fuck you and your invasion of my privacy. It is my own little way of silent protest.

I assume I'm in a minority though and most people don't care. Most of the time I use an ad-blocker. iPad doesn't have a solution unfortunately.
