Because they were deceived by Apple's quality promises? If Apple really wanted to improve security (instead of just producing marketing claims about it) they would provide anyone with debugging symbols, root privileges and anything else needed for research and debugging.
> Because they were deceived by Apple's quality promises? The point being, with Kaspersky as security experts, it really does call into question their judgement and expertise.
1. At some point, weigh probabilities of exploits
2. Update Bayesian priors as new evidence arrives
3. Even if the initial decision currently appears incorrect, there needs to be a high enough difference in probability to justify switching, because in switching, you're still exposed to any persistent exploitation via the old exploits plus new exploits on the new platform
Switching back and forth the instant your Bayesian prior swings over/under 50% for Android being more secure than iPhone is a terrible strategy. (Also, you need to risk-weight your various exploit probabilities... security is a multidimensional quantity, so collapsing to a scalar is at least context-/threat-model-dependent.)
