GamerGate is not a partisan movement.
I would partially agree with the statement, but the truth of the matter is that the only media outlets that covered gamergate largely were Milo Yiannopoulos and Christina Hoff Sommers, who are both associated with right-wing organizations. If you ever monitor the ongoings of Gamergate forums, there is much bellyaching against "leftists" or "SJWs" from a slice of the population that doesn't really have too much interaction with politics at large. When these kids see corruption within their small sphere of awareness being hand-waved away as being only cover for misogynists, it is very easy for bad actors to blame corruption on the "liberal media".
Many of these gamers are kids that don't read the news or follow politics much at all. They have no sense of history to understand that for most of human history up to even a few decades ago, women were largely seen as property. They see "feminists" as outsiders trying to destroy their main source of entertainment.
But now, all your online activities are recorded pretty much permanently for everyone to see (sorry, privacy policies or settings just encourage people to spill the beans).
Or they could re-release their history as a special edition with revisions, and wait for the original copies to go obsolete.
We want to take our current content and all the stuff that matters to this community and deliver it on a site that still speaks to the interests and habits of our current audience, but that is, at the same time, more accessible and shareable by a wider audience.
I think the problem is that if you build an engine for a wider audience at the cost of the community, you'll be left with nothing. There are plenty of other "shiny" websites for the mass audience. The community that was built at Slashdot is the real value of the brand. If the parent company wants to build a website with a mass appeal, they should build one from scratch and spin Slashdot off into a separate company.
