This is just an ugly side of humanity that has always been there, but is magnified by the combination of anonymity, disenfranchisement, and ever more addicting Skinner-box style entertainment. We are a tribal species; in the past this type of behavior would be socialized out of you or else you would be a recluse. You didn't have the opportunity to sit in your own filth and project your self-loathing onto anyone acros…
Playwrights hundreds of years ago didn't like people publicly disapproving their plays, or low ticket sales due to bad word-of-mouth. People have been conveying disapproving reviews for as long as people have been doing something which can be reviewed. That hasn't changed even though there are so many more things which can be reviewed now. There's nothing unique about this situation in the context of video games.
What's telling about this article is that the phrase "free speech" doesn't make an appearance or get any serious consideration. Free speech means people will say things you don't like, convey ideas you disagree with. A principled approach to free speech is not censorship -- "moderation" as the first screenshot complainer is said to have written ("If I quit gamedev, it wont be because of money, or lack of love for the craft, it will be because of the attitude of the vocal 0.1% of gamers who nobody will moderate."[sic] some uncredited person allegedly wrote). Calling a harangue "abuse" is an attempt at conflating something dismissably rare ("0.1%" we're told) and indistinguishable from free speech with actual abuse. We're also told that stalking a game programmer's family happens less frequently than someone's harangue. But virtually no exposition is wasted on something which could very well be genuinely abusive of someone else.
If the disapproving reviews come from such a small minority, they should be easy to ignore or skip past, and one should gain practice in using their advanced technical skill to make a computer not show them what they don't want to read. Also, readers can choose their reaction to seeing a screed; talking about them as abuse victims denies their agency. They don't have to choose to be an alleged victim (the "abused"), they can choose to conclude that someone who replies with "CUNT" repeatedly (as "SaintNick" replied to "ChineseRoom") is irrational and not to be taken seriously.
And please stop talking about "voting with your wallet", a phrase that can be justifiably be said to mean that one intends for wealthy people to deserve more "votes" than poorer people. It should be sufficient to explain that one could choose not to buy the next game that publisher releases, which is probably what one meant to say in the first place.
