First there were the allegations that Zoe Quinn was boning some journalist in exchange for good reviews. This was ultimately bogus, but a bunch of gamers have since banded together against that sort of corruption in video game journalism. Even though that specific incident was not true exactly there is still a lot of corruption in video game journalism, where certain critics from certain publications are given perks, kickbacks and favourable access to the latest products in exchange for good reviews.
Then a splinter group of misogynist idiots started attacking feminist critics who were critiquing the video game industry for (still) being blatantly sexist, under the guise that these feminist critics are also corrupt and playing favourites. These idiots are the ones who have been threatening feminist writers like Anita Sarkeesian.
The media jumped all over the rape and death threats and painted the whole 'movement' with the same brush, thereby quashing the criticism from the greater group of gamers who are peeved at the way the incestuous relationship between the video game developers and video game reviewers has tarnished the integrity of video game criticism. So all those people who are pissed off at the video game reviewing industry for being in cahoots with the developers are now painted as misogynist virgin nerds who are angry about the effect of female developers and less overtly male-centric games that are and will be coming down the pipe, because it's attacking the "gaming culture" or some such BS.
So then all of those people who have legitimate beefs with the integrity of video game reviewers are now pissed off at so-called "Social Justice Warriors" who have glommed on to the feminist cause and are painting them (the gamers) as misogynist virgin nerds because it's 1) insulting, and 2) squelching legitimate criticism by using feminism as a rallying point even though it has little to do with the overarching issues that these gamers are mad about.
At least this is the play-by-play as far as I can tell.
