No, I don't expect perfection. However, I do expect very careful implementation of access management for very large databases containing lots of PII and other sensitive customer information. Things like huge databases being accessible without credentials shouldn't require perfection on the part of some human. That sort of stuff should be continuously audited in an automated fashion.
But the software industry is quite bad, as a whole, so even the relatively competent actors make surprising, high-impact mistakes.
Maybe it's because the stakes are relatively low (c.f., bridge collapsing vs. PII leak) and the competition relatively fierce? Maybe software engineering is still very young and moving quickly?
In any case, I think it's totally reasonable to hold the opinion that MSFT is doing things pretty well relative to the rest of the industry and also that the industry as a whole is doing a pretty poor job.
IDK, for me the story has to be one of the following:
1. MSFT made a huge and inexcusable mistake, so maybe there's something systemically wrong with MSFT; or,
2. MSFT is very competent, and even very competent people are making very big mistakes, so maybe there's something systemically wrong with the entire industry.
