I just watched the MuseScore video. I get that he’s trying to be entertaining, but he just comes off as a jerk to me. Doesn’t make him less correct of course, but do we really need a blood-vomiting Shostakovich or imagined email exchange making fun of “New All” (among other examples)?
Honestly, it’s disappointing that this is the default way to criticize someone’s work, however bad it may be.
Imagine if your users, teachers or even parents critiqued your work in this way.
