What kind of iffy politics? Only thing of what I see coming from his channel that could be considered political is complaining about government surveillance which is problematic for many regardless of whether they're right or left. Other than that it's not like politics are a talking point on his channel.
At this point if the users want to continue using Reddit, that's their choice and I don't think holding a subreddit hostage is gonna help. I like the non-intrusive suggestions such as promoting alternatives. The users ultimately decide whether the platform survives. I'm staying on kbin because I don't like the direction Reddit is (has been) going, I'm just glad this whole situation enlightened me to good alternatives. This is just one more step in the wrong direction and people will continue to leave if they continue to make the user experience worse.
