To be credible, it would be especially true for a competitors product. If you're even remotely insinuating that they can or should go softer on themselves than others, they're 100% not credible, and that would only make Apple's stance that much more legitimate. If they aren't at least as tough on themselves - and they should probably be tougher on themselves than others - it's just a marketing team.
But I do think they have that responsibility. Disclosing flaws and vulnerabilities for consumer use cases requires nuance and less "just the facts, ma'am" otherwise you're actually doing more harm than good.
The stories will be blown out of proportion, and the world will go numb to them. Because the little, low impact issues are constant background noise - when they get blown out of proportion and 0.000001% are affected, and 90%+ were patched 6 months ago, all this does is contribute to the noise, and doesn't improve the signal.
