Hundreds of millions of businesses (and individuals) transacted $83 billion to Microsoft just last quarter, so clearly they're doing something right.

Any "big enough" organisation will eventually do something stupid, disgraceful, or even illegal. Once you have over a hundred thousand staff, there's just no way to guarantee that they all row in the same direction and nobody gives in to the temptation to cut corners or outright cheat.

If you think you can judge the entire rest of an organisation by a few bad actors within it, you'll be perpetually disappointed.
