What is sad is that ad-blockers would have never become a necessity, had advertising remained fair (as in: static images, no code execution on browser, no tracking).
When there's a profit motive, someone will always cut corners.
This only works as a specialisation of "people". Where there's no profit motive, people will also cut corners.
Once enough people do that, the users install adblockers, which also hurts advertisers who were not filling your screen with shitty, laggy, possibly dangerous ads.
