Basically developer of Edx accused one developer of Lsp making an "rm rf" pr to their github repo in May 2020, leading to the data lost of several user. Now there's flaming between the two teams. (it's a chaos, lets just sit still and see what's next)
I remember that PR. I recall it was a joke, but the build system auto-compiled after every new commit, so a few unlucky people who enjoy life on the bleeding edge paid the full price for that strategy.
