Some people would rather no one can get the content than simply not consuming it themselves. It's not enough that they don't see it: No one should, because they know what's best.
Are those articles advocating that youtube ban him from the site? Are they arguing that he should be arrested, or prohibited from creating his content? I don't think they are.
What the articles critical of PewDiePie are saying is, "here is what he said and why we think it is offensive and why we no longer watch his channel. If you agree with us, you should also not watch his channel"
Everyone is free to read this opinion and then decide for themselves if they agree with the writer, or if they want to keep watching. If it turns out that so many people agree with the articles that PewDiePie no longer has an audience large enough to sustain him, then that sucks for the people who DO want to keep seeing him, but is just reality. If not enough people want to watch content of a certain type to sustain the producer, then that content will not be produced.
