Because it seems, the issue was brought on by the community that Fb has constructed to tie all of its computing options collectively.

Merely put, Fb was not hacked. There was no massive conspiracy to silence the individuals. Every part crashed attributable to a mistake made by the corporate itself, and its safety measures made it harder for its engineers to repair the issue. that was it.
