Even DNS traffic and IP address and packet metadata is extremely valuable to ISPs like Comcast and AT&T. They use it to control what you can and can’t do – for example, throttling your access to streaming video services that compete with their own streaming products or partners’ products. They spent millions to overturn Net Neutrality regulations so they can use what they know about your traffic to monetize you (steer you to their products).
I use Moz too. It works pretty well, but I do get a lot of “confirm you are not a bot” messages from Cloudflare, especially when I’m using LibreWolf to anonymize my browser headers (fingerprint).
