Slice seems super disruptive, and i have some concerns about centralization, because with slice you can block ads on the website, and then u can view ads from slice instead, but that means the website dont get any money but slice does. So its very disruptive? And what if slice ends up controlling the whole market, via this kind of "bait and switch". Then it becomes very centralized :) But lets see
It's up to you to install an ad blocker, Slice does not block other ads.
