Finding additional ways to waste more of people’s time on the web isn’t a good solution to anything. Doing so in a privacy invading way from a company that has a vested interest in collecting as much data as possible, exhausting all utility from it and butters its bread in an industry which specifically is built around disrespecting the time of other people is just never going to fly.
