I reached out to @linuxfoundation on this matter (banning a person from attending a Linux Foundation conference after a public report of him wearing a red MAGA hat) and, as yet, have received no response.
@jzemlin: Mind checking on that? I'm hoping there are crossed wires.https://twitter.com/unclebobmartin/status/1192849901786484736 …
After reading some of the commentary there seems to have been some incident, which would've maybe warranted that level of response, but I'm sure that MAGA hat didn't help. Though details seem to be far and few between, a lot of people just implying something happened.
