Context is everything. They had every chance to own up from the day of until now. A ‘lulz haha we goofed up’ in a nerdy security conference doesn’t seem like the right place or time.
I'm not sure what your definition of "own up to it" is, but they issued an apology day-of.
Apologies don’t mean anything from a c-level suit (George Kurtz) that has known history of causing outages. The culture at crowdstrike of being accountable is a facade.
Got it so to own up to it that have to change the culture... Overnight?
