@drekly @Plswrk, nobody needs to work for free, but creating incommings by spying the user to sell his data to third party isn’t an acceptable way to gain money. There are a lot of methodes to gain money in the network, but with surveillance advertising spyware is the worse and with big risks for the user, which can’t control where his personal data ends up.
@drekly, simple ads are not a problem, if they are based on the content of the page and not based on user logs. Ads as is only can be somewhat annoying if there a lot in the page or they appears in the middle of a concert in YT, but no are a risk for the user privacy, no more than a commercial poster in the street or an ad in TV. As with all, bad the abuse. Years ago you saw 1-2 banners in a page, but novadays you must seek the webcontent between advertisings, banners, cookieadvices and popups
