When exactly was this mythical time when not toeing the line came without consequences?

I'm not sure, I'm just as confused as you about this mystical time. I don't remember ever mentioning a time where words didn't have consequences, just when you wouldn't lose your job because someone across the country heard you say something they didn't like.

The internet and the IT industry used to be a lot more free-form and libertarian, where people could debate or advocate almost anything.

I think you managed to perfectly exemplify the point parent is making. Stallman never argued this, but in the frenzy of outrage his points are being misconstrued and he is villified to rationalize the punishment he has received.

he downplayed the severity of it with his wording, which is tacitly arguing in favour of it

I mean, RMS definitely wasn't helping by any means but I think "tacitly arguing in favour of it" is kinda a leap.

I get being mad he wasn't helping but thats a looooong way from supporting the human trafficking.

Not what this was about.
