Tiny resume:
Reedit is changing its API price (up to 20 million $ per year) to the third party apps that offers accessibility to ddisabled people, no ads, no porn, and also it offers better tools for subreddit moderation, things that the official reddit app doesn't.
Basically the blackout consist in going "dark" 2 days, from 12th to 14th. (or indefentely, some communities like r/ProgrammerHumor prefers to go dark indefentely)
I hope this doesn't break any rule, if so mods please feel free to delete my post but at lease consider what people is gonna vote.

Since we are sysadmins, i think we could join this blackout, we know how much painful can be this type of things irl, so i think we could join them.

BIG EDIT:

Mods, with all my respect to you, the community has spoken, we want to join the protest. Please respect our choice as we respect you too.
