"Correlation does not equal causation" is a very important and pertinent concept in statistics, and I think we should aim to actually understand the concept instead of just trying to warp the meaning of the words to fit the example

The bug simply was not "a good example of correlation does not equal causation" as any statistician would use the phrase. That's my only point. OP is free to type whatever words he wants into the comment box and press send

It might appear as a correlation due to sampling error, but the two variables have no dependence with each other. There is no correlation with it being February 29 and the bug that was described.

It's not. There was no correlation at hand here - this was just a coincidence
