You can think it's a joke, but I agree with parent completely. Ultimately, it doesn't really matter, since I get to choose what runs on my hardware, and I choose not to see ads.

I don't steal from or scam stores even if I can get away with it, because while I don't deep-down care if they make a profit, I do feel it's wrong to cheat them out of it. If I want what a store is offering, I feel like I should deal with them fairly. If I don't want it, I just don't patronize the store.
Their program (Server) may ask my program (Browser) to do things and my program may deny ANY request based on ANY criteria that I get to set. My program is under no obligation to do anything their program asks.
This is all perfectly reasonable and fair.
