I don't think that's the purview of browsers. Browsers are, however, responsible for maintaining a good user experience, so the length to which ads and tracking scripts, like pop-ups of years before, create a poor user experience the browser is right to take measures to block bad actors. I think limiting the number of ad/tracking scripts is a measure towards that.
