Ads can exists, I do not have any problem with it. I think that we need to have tools and techniques to avoid them. If the medium doesn’t let you use those tools, it’s right there where I have a problem: Ads in a magazine? Just change page, Ad on TV?, just change channel, Unskipable ad? Woah woah woah. YouTube, dear, you are forcing me to watch something that I don’t wanna.
