That wasn't the argument OP was making. He was making a (legitimate, IMO) objection to RMS' rhetorical style, and saying that it makes many people not want to read his writing. OP never said that this makes FB blameless.
If the OP doesn't intend to defend Facebook against RMS's claims, his criticism of RMS's rhetorical style is wholly irrelevant to his core point and, in turn, this discussion.
That's not true. You can criticize that which you respect, in order to improve it.
Yes, let's criticize arbitrary off-topic things ad infinitum, because we can.
