I think it's more than clear even if the WHO doesn't intentionally want to use this to kill off gaming (or "the wrong kind of gaming"), someone will.
We need to act now.
The WHO gets 75% of it's money from volunteers, and 25% from member states.

IMO, dealing with WHO is like dealing with Youtube/Google. Both have mammoth warchests, but are deathly afraid of bad PR and the money fountain slowing down.
Possible plans of action:
> Dig and Create infographs mocking and informing the public. Put them in ALL gaming related hashtags and ALL mental health related hashtags. Don't play nice, get in people's faces about it. The goal of this is to reduce volunteer donations, and cause bad PR internationally- until it becomes a talking point amongst politicians.
< Infograph (A) - Anti-Chinese. Show evidence of Chinese lobbying for gaming addiction, and how their own "treatment centers" end up killing people- all the while buying out Unreal 4, and trying to get their games into the west. Paint it as China trying to kill their competition in an underhanded way. Then anti-China hype is still big amongst US patriots and Trump supporters.
< Infograph (B) - Defamation. Expose the biggest fuck-ups the WHO have made on mental health before, their own staff being hypocritical, and/or money being a bigger motivator than actual health. People only trust faceless organizations because they know nothing about them. Make it a talking point, and it'll become memetic to hate that group- much like the excessive health & safety regulations of the EU (and far worse crimes in recent history).
< Infograph (C) - History. Show how other hobbies have had psychos pinned to them by a busybody politician or body, and it didn't stick due to overwhelming common sense; sick people will do sick things, sane people won't. Then draw comparisons to what the WHO are doing now. This appeals to gamers (old and new) and those who might have other reasons to loathe those pinning shit they didn't do onto them.
< Infograph (D) - Anti-SJW. While it'd be preaching to our own, a lot of people are turning against the hard left whackjobs. Show how they've been going after gaming, and how the WHO's decision could mean that instead of claiming gaming makes you crazy, that everyone who games is already crazy. Not to mention the violation of freedom and danger it proposes to brand someone as insane because they like something. Appeals to the right, pro-trump; and as it says, anti-SJW.
< Infograph (E) - Slippry Slope. Show them how South Korea and China deals with Gaming Addiction. The social pariah it makes you, how it affects your credit score, how it affects your chances at a job, and how those who are "treated" go through hell. It's not fear mongering, it's a possibility. If smokers and drinkers are less likely to get organ transplants, why shouldn't other "soft" vices also have some restrictions. Clearly, anyone who games is a waste of a human being. Appeals to gamers and those who have been falsely branded over addictions or obsessions they didn't have.
> Request your government ask about it, and explain your concerns. A politician will say and even do whatever they believe will give them votes or PR. So give them a story they can run with- big bad WHO trying to brand healthy patriotic consumers as insane because they enjoy their hobby. You're not asking for them not to do it, but they need careful guidance to ensure they don't over-step their mark. After all, they wouldn't want the whole US/European/[your country here] gaming industry to collapse and harm the economy. BAM, you've told them it's pro freedom, pro consumer, pro economy, and they don't have to stop it, they just have to make demands and wag their finger- all bad PR for WHO again. Call/email your senator or equivalent.
> Request Youtubers you like cover this topic. A short video is easier to pass around, and something about videos just makes fuckers click it rather than read an article or text on an image. If they spoke against SJW, bad game journos, or for artistic freedom- odds are that'll be good. But don't be afraid to try big youtubers as well. The more eyes we get on this the better, right now it's only known to a limited part of the gaming community. If you get someone like DeFranco or PewDiePie, then it blows up too fast for WHO to effectively PR, as people ask stuff. And hasty answers can be used to hang them later.
