Opinions are about as good as pissing in the wind. I disagree with their opinion.
However, there is something to be said about 4chan and gamergate links. How and why this started is something we should examine, because there are concrete links that are much more based in fact than opinion. But because the author decides to link things without context or actual correlation it actually obscures the whole picture.
Just because one person in a group (or a small amount of people) do something does not mean the whole group approves of or condones it.
Games have never been more popular, and they continue to become more and more mainstream every day. You can use the same argument for anything, and logically it doesn't prove anything.
