That's not the student exercising their free speech. It's the student denying the benefit of free speech to their fellow students and the rest of the university.
The university apparently hadn't yet educated the student on the basics of university, and there was not yet any sign that the university was going to. Reporting followed up with the student, when they promoted their personal brand, and solicited funding to continue their fight.
(You might be happy to know that, instead of my modest donation going to the university with the student who thought a first-rate university was the place to ignore the fundamentals they teach, and instead play self-promoting influencer... IIRC, that was the year the money went to a homeless trans person, who'd been through more hell than most people can imagine, and who needed a discreet laptop so that they could practice coding job skills, but without the laptop getting violently stolen from them in whatever shelter they could get into. I'm not making this up, and the contrast was striking.)
Regarding your other comments, much of the rabid left didn't seem to be acting as the savvy political operators you suggest: a whole lot of people were mindlessly flinging their poo, and playing right into the hands of some of the worst of their adversaries. Maybe it was partly a combination of crisis mode over the best of intentions (e.g., help those who need help), and anger and fatigue from same (which I certainly felt), but there also seemed to be a whole lot of not knowing any other mode of reasoning or acting. Maybe that's not their fault -- you might blame the deterioration of popular journalism, social media sites preying upon their users, and a dearth of visible role models demonstrating anything else -- but that seems to be where we are, for large slices of the vocal population. And there's been a lot of counterproductive.
