Freedom. What is being defended here is the right to have a website like this at all. The west has a long way to go to wake up to what's at stake here.
Patreon isn't against "freedom" and they most certainly know what's at stake here. What they're against is having to decide whether a cause is just or not. After all, one side's "freedom fighter" is another side's terrorist. In this case it might be pretty obvious, but they don't want to get in the habit of having to make calls, because there are far more cases that are less clear cut.
