Which wouldn't be so bad if they didn't form the majority (or at least appear-to, judging by the net-effect of everyone interacting in the public-sphere).
Like @zo1 said, we don't really know the real landscape either. Just think of how little it takes to silence someone like Marc Andreessen. Now think of all the commentary people in tech don't say, especially on social issues, because the online masses with pitchforks will be after you.
Unfortunately that's the way it is for a lot of people after a certain point. The only counter example of this in tech I can think of is David Heinemeier Hansson.
Okay everyone took this a bit too literally. Obviously I don't mean he was literally silenced. But I would bet he's self-censoring a bit more: "I now withdraw from all future discussions of Indian economics and politics, and leave them to people with more knowledge and experience!" which was then followed by five tweets to explain the original tweet. That kind of reaction has to influence his willingness to speak on other topics not directly related to tech.
