This popped up earlier today for me, thought I would share. There is some irony in this being thought of as a crisis, when you compare what has happened in Greece for a very, very long time now. Does not really come up with any real conclusions, but I can't say I blame them. Lots of theories going around (and I doubt the coronavirus lockdowns are a great explanation, considering we're nearly four years out from them).
Tifo also did a piece of Savvidis back in 2018, after the incident that shall not be named. Weirdly, it spends basically no time on the actual incident.
