It is logical that many developers finance themselves through third-party advertisements, but it is not admissible that they do it in an invasive way and also use trackers that virtually spy on user activity.
If I see, for example, a concert on YouTube, I would not be bothered if a banner with an advertisement appears at the bottom edge of the video, but if I find the artist and the user outrageous and disdainful to randomly interrupt the concert with an advertisement for minutes, even long infomercials. This benefits no one and makes an adblocker essential.
Also in various pages with animated ads that slow down the load and steal the bandwidth that the user pays, in many countries with a good amount of money.
Companies are bombarding us with ads on all sites, in apps that we use, even paid ones, but not only on the web, also on the street on every corner, on television, the mailbox at home is always full of Spam of all kinds. This is not the way to make money, it is simply harassment and I certainly salute any measure to block them and even more so the trackers.
I think there are much more discreet and fair methods to make money online, instead of the so crude and offensive method of 'foot in the door'
