It's fair to be critical of this study. However it's important to be aware that the CDC is conducting their own investigation of myocarditis and myopericarditis associated with vaccination. The CDC reviews VAERS reports and then actively investigates them, keeping a tally of the cases that meet the CDC's own stringent criteria.
According to the CDC (as of August 18th), for males age 16-17 the reporting rate of myopericarditis after 2 doses of Pfizer is 71.5 per 1 million doses administered (0.0071%). For males aged 18-24 the reporting rate after 2 doses of Pfizer or Moderna is ~37 per 1 million doses (0.0037%) [1]. They note that for males the observed cases exceed the expected cases by a significant amount in age groups through 49 years.
> myocarditis occurs at a rate of about 200/million in general
For accurate scientific discussion it's important to stratify by age. Following the reference chain from your citation, the important nuance is that "more than one-half of all cases [of myocarditis in the pediatric population] are seen in the first year of life" [2]. Consequently the incident rate you've cited isn't quite as representative as you suggest. This fact is in alignment with the CDC mentioning that the observed cases of vaccine associated myocarditis are greater than expected, particularly for male teenagers.

I disagree - the title accurately reflects available evidence and official data from government sources.
> that's going to cause people to run scared
People shouldn't be scared by this data. The vast majority of young adults recover quickly from clinical and subclinical myocarditis [1], although the long-term effects aren't well established. It's important to note that viral infection can also cause myocarditis, so this phenomenon isn't just a knock against vaccination. The takeaway is that these findings are an important factor to consider when considering vaccination strategies for children and teenagers - we should proceed with an abundance of caution, but not fear.
