Re: Have they started to employ Microsoft staff or what?
As with all mostly open source software with a Huge user base, the level of bug detection is quite high, so the bug complexity and use cases fall quite rapidly as the project matures.
iOS CVEs 2019 = 156
Android CVEs 2019 = 414
iOS Market Share = 24.6%
Android Market share = 74.3%
so androird is roughly 3 times the install base and roughly 3 times the CVEs, so simillar to CMSes the vulnerability rate looks similar to market share, i.e. bug detection goes where the users go.
