My experience with people going after corruption (n>3):
No one is perfect. Everyone breaks some laws, does something taboo, holds some controversial view, or does something improper. If you're going after power structures, they'll take that and pull on it to destroy you unless you back down.
This was done to an extreme in Communist regimes. For the most part, people didn't go to prison for criticizing the government. People who criticized the government went to prison for some other, complete inane but technically correct reason.
For a public examples, See Hunter Biden. Compare to Donald Trump. Yes, there appears to be corruption with Hunter. No, it's not out-of-mainstream for DC. Yes, it's greater than Trump's family. Only Biden has the resources to defend himself -- half the country is supporting him. Unless you're a presidential candidate, something like that WILL take you down.
Allowing that to work really benefits the power structures who can do PR and hire investigators. And it really harms anyone out of the mainstream or with unpopular views, where a simple cancel culture can kill your career.
Were there people who didn't care about the issue at hand but just wanted him to go for other reasons who opportunistically seized upon the issue to finally rid themselves of the troublesome monk? Of course, and I have some particular people in mind. But the converse is also very much true. RMS is a complex person and you cannot pull but one thread from the fabric.
> And compare the treatment he gets to other people in position of power.
That's simply whataboutism, not an argument. The rms issue is the rms issue. I would be delighted if you worked on some of the other injustices in the world as well.
RMS has suffered a crippling emotional blow but he will get back on his feet. In these regards rms is hardly unique: he grew up in a community of people very much like him, many of whom routinely make far more shocking statements than he ever did. Leaving that environment for Harvard, and later MIT demonstrated and developed in him an ability to learn, which few apparently can see (and which even fewer possess themselves).
