> These opinions very from nuanced points on free software, to the crazed ramblings of a conspiracy theorist.
I've not seen or heard any "crazed ramblings of a conspiracy theorist" from Stallman. You may not like what he has to say sometimes, but I've always found that his arguments are founded in reason.
> This all said, letting Stallman back in after what he said, and his characteristic refusal to apologise
Did you mean "after what people accused him of saying"? Because, as is typical of the hyperbolic blame culture of Twitter and such, he didn't say what he has been accused of saying.
> makes it very hard to argue that the FSF is an organisation that represents the movement.
Which movement do you mean?
Free Software, by definition, doesn't care who you are, what you do, where you are, what you say or think; neither now nor in the past. So long as the FSF does what's best for the Freedom of software, it continues to represent the Free Software movement.
