So, I think OP is saying, please don't shout simple slogans about complex issues.
Realistically, the level of effort I'm going to put forward to defend some person on the internet's right to make a particular comment is limited approximately to "writing a comment myself."
Defending to the death? As in risking my life? Maybe if someone's violently asserting a right to regulate what everyone says, or even some particular group says, if I don't think they can defend themselves. But one person under non-violent threat? I'll surprise myself if I make it off the couch.

I think you missed the point of philosophy. It's pretty much all about pondering questions you can't answer. Once you manage to answer them, you're not doing philosophy any more but have moved into the realm of science.
However, this discussion about philosophy and freedom is the reverse: people are already fighting and in many cases dying for what they think is this thing called 'freedom', and yet it proves elusive to find a definition.
The real-world, societal impact is already there. So it's worth studying.
And if you study it and find that it's elusive and nearly impossible to pin down... well now that's interesting, and should make you think critically about anyone who uses the term as a low-nuance bludgeon in an argument.
(In the other article around Twitter here today - this thread - https://twitter.com/yishan/status/1586955288061452289 , I think this point is made pretty clear early on by the spam example: perfectly legal, yet "bots" are a self-professed problem for pro-whatever-speech-is-legal,don't-get-involved-further Musk...)
All definitions are ill-defined if you're willing to question the words in the definition.
Maybe the point of philosophy is to uncover the weaknesses in our understanding of the word, rather than gain confidence in understanding it. So, asking "am I free?" helps me uncover my assumptions about the world and find out exactly how many levels deep I'm willing to go before I trust that the words in the definition are true.
Sounds to me like the outcome was pretty positive, you came out the other end way smarter than most.
“Freedom” is always “freedom to X”. The real debate is about the X, not how to define the word “freedom” itself, which is comparatively trivial, and doesn’t have much bearing on the X part.
I will say though that I find authoritarians and their sycophants far worse, hypocritical and dangerous.
That's my take on it.
