Have you read the email conversation in question? Surely it made you concerned at least a little in regards to the state of FDO and RedHat?
Thinly and not so thinly veiled threats to another person to police their own, not related to FDO in any way, shape or form, community because it does not adhere to your political ideology sounds like a severe abuse of power to me.
FDO is a community, and having people be treated with respect is crucial for maintaining this community. Letting people with a history of not respecting others be a part of that community is a problem, even if that behavior was displayed elsewhere.
It doesn't address the contents of this particular incident, rather it alludes to vague and nice-sounding moral principles thereby brushing off the whole specific issue. It is interesting, because by staying general the author gets to shrink from taking the responsibility of giving their actual opinion on the specific incident itself.
I don't remember since when "bowing down to threats" is adhering to CoC and "openly threatening someone over resolved conflicts under the suspicion of wrongthink" was "respectful behavior from community representatives".
Either way, it is always "we're just policing the bad people" until the bad person is you.
