Your entire post is about information security researchers and bug bounty programs which is a different discussion. All platforms have 0-day vulnerabilities that are exploited, mainly by state actors. Apple is the least transparent. People seem to go senselessly crazy with their marketing BS as if it triggers some primal instinct.Let's not move away further from the truth. You'd expect a company that advertises security and privacy of their users for a most part of the last 10 years, would also value the effort and time of white-hat ethical hackers and security researchers. Instead, that is not quite the case.
Apple paid the least amount of bug bounty program among the Big 3 (Microsoft and Google) . And not only that, independent security researchers found it more frustrating to work with Apple, sometimes not even crediting or paying them for discovering the vulnerability.
Data from 2019 to 2022 shows that Apple lags behind Microsoft and Google in terms of bug bounty payouts, amounting to $20 million. During the same time, Microsoft paid close to $40 million and Google over $30 million.
Now, you may argue that since Apple’s products/services are more secure, the bounty paid will also be less due to less discovery of bugs. However, that's not the case because clearly Apple has a bad reputation in the independent security research field.
All of these above-mentioned data points to one thing: actions speak louder than words. Apple's privacy and security ad campaigns are more to benefit them and showing who is the boss, rather than benefiting the user. It would be better if Apple can put their mouth where their food is and start respecting the hacker and security community like Microsoft or Google, both of which ironically does not advertises security and privacy for their products.
Here we are talking about every app on Android being provided an open field to indulge in whatever data malpractices they wish to partake in. The aforementioned 0-day vulnerabilities, irrespective of credit, are always patched on iOS, even on 6-7 year old devices. If someone is concerned about security and privacy, then they would be most concerned about Android, followed by Windows and then iOS.
