Only to unreasonable people.
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.
Hyperbole much? He wasn't silenced in the slightest (which would be difficult to do, given the amount of money, i.e. power he has).
If getting a deleted tweet reprinted in several tech publications and on the top of HN is being "silenced", I would love to be silenced more.
