I will point out that you only talk about stylistic issues and do not actually address the central point of the article, which is that language matters ("terrorist" or "freedom fighter"?) and that the discourse using these words is influenced by it.
A discussion about freedom fighters is a different one than a discussion about terrorists, even though the people involved might have committed the exact same crime (shooting a bunch of people).
As such, designating the mob as American Patriots and the event itself as a "riot" or "insurrection" instead of as a "coup" is - indeed - important and very telling.
A defining feature of this era is that language doesn’t matter, starting with "fake news" in the summer of 2016. Riot/protest, fascist, coup - these terms and more have been co-opted and reflected back at the other side. Same words, different meaning in the opposing context.
