If you mean “someone” as in an individual that is posting something they made that happens to contain the song, then I agree with you.
But there are many other uses where there should be restrictions (and need to pay royalties/get licence), like here where it’s being used in a political campaign, or for commercial purposes, or if being posted by a corporation, etc.
This sort of campaign isn’t designed to sway your average undecided Joe.
It’s meant to reinforce the indoctrination of those already mildly radicalised, pushing them to the extreme. They will inevitably pull along some other inbred imbeciles along with them, and if they’re extremist enough and numerous enough, something like the invasion of the capitol would have worked.
Note: it’s not only morons who get swayed. Elderly folk are especially vulnerable to this sort of explosive statements, they have a tendency to believe what they read or see (on TV or other platforms) disregarding their own better judgement…
