I think its pointless. Warframe is not a big enough community to have any impact and frankly none are. IMO this is doing more harm to the community then good. Redits decision will likely not change.
This is accurate. Whatever your feelings about reddit are, the warframe sub is a major artery for DE as far as advertising, community interaction, feedback, and even bug reporting are concerned. Can these things still be found on other sites like the forum and discord? Of course. Will the thousands and thousands of people who still use reddit as their easy-peasy news website shift over to those places just to get warframe news? Not all of them. Keeping the sub closed just hurts DE, no matter how you look at it.
