I never personally interacted with Near, but I've been following them and their work since the days of the zsnes forums, back in the mid-00s. I'm a huge fan - not just of their technical achievements or their ideological commitment, but also of the seeming grace with which they carried themselves in the past few years. I don't know if I'll get all the details right, but I'll try.
My understanding is that KF chooses to harass people who are marginalized, easy to bully, and on the basis of how dramatic, embarrassing, or "cringe" their response would be. Near was gay, autistic, non-binary, and involved with furry communities (though IIRC they may not have been a furry themselves - not that it matters), which made them an easy target. They were sensitive and struggled with depression - KF knew their harassment would be effective. And Near was a controversial public(ish) figure who'd, in the past, courted a fair amount of scene drama and flame wars (sometimes blamelessly, sometimes not, as I'm sure they'd tell you themselves) that occasionally got very personal. In other words: KF looks to stir shit up, and Near sadly provided an ample amount of shit to stir.
No one deserves to be harassed like this, but it feels especially cruel that it was done to someone as remarkable as Near. This is a terrible loss.
