Why? It's almost always noise nobody wants to see. Advertising hurts usability by definition. Putting ads in the address bar of all places is actually hostile to users: people who are used to finding bookmarks that way will end up opening sponsored links instead due to muscle memory.
It's great to have an out. But are those synchronized? Because I find the increasing number of tweaks difficult to remember. Tyranny of the default is real.
Why not? The bills have to be paid. Wouldn't you rather they monetize their product in a responsible way than join the others? We live in the real world after all.
The responsible way to monetize something is to charge for it. Advertising makes it normal to have "free" products and people become slaves to it. Can't say or do anything they don't like lest they kill your income.
That's exactly what everyone should do. Instead of letting them get away with it, we should block it all unconditionally and by default, forcing them to find another solution that's acceptable. Linux distributions in particular are in the perfect position to patch this out and improve user experience for all their users.
