Its looking a bit hyprocitical here to be honest. If you use websites in the web today, you are sending data for sure unless you use a adblocker that blocks analytics as well. Brew collecting data this way is unethical but complaining about these things these days is not going to do any change to be honest. I would be glad if the people who complain about this dont use any websites that collect data without giving any control to the user. But we all know the real deal.
