They say that. But with closed source software we can't verify that it's true. I'm not saying they don't care about privacy, only that we don't really know if they do or not.
Plus, with open source you can verify intent, which you can't with apple.
Which provide a device getting your finger prints, all your phone numbers, internet search, bank details, some paiements, network communication, voice communications, text communications, localisation using GPS and wifi + hotspot + phone towers and soon ihealth device collection body metrics.
And they are profit oriented, not people oriented.
Sure but they were there for years before anyone noticed. Same with PHP's Mersenne Twister code. Same with multiple other long-standing bugs. It's disingenuous to toss out "Oh, if only it was open source!" because reality tells us that people just plain -don't- read and verify open source code even when it's critical stuff like OpenSSL.
I agree that failing to fix a problem like this in a timely fashion is bad, but sins of omission are generally judged differently than sins of commission, for better or worse. Apple failing to apply proper prioritization to security holes isn't the same as Apple collecting data to be sold to the highest bidder.
So, again, Apple should not be treated as equivalent to Google and Facebook. Feel free to judge them harshly, but don't paint them with the same brush.
Apple has implicitly for a long time, and lately much more vocally, cared about privacy. They don't have the same data-driven business model that Google and FB do.
