Just reporting it by email! Why does that mean they thought they were following someone else's idea of how to do disclosure? It's not called firstname.lastname@example.org is it? Maybe they'd never heard of CVD. Maybe their idea of disclosure is to email and then Tweet it as well.
Do you see what I mean though? You snarkily ask 'maybe I'm wrong but this doesn't look like X' when nobody ever said or implied it was X. It doesn't make any sense as a criticism.
So, to explicitly say they weren't aware of 'x', when it doesn't match the timeline, is also - in and of itself- possible disingenuosus. Do you, at least, see where I'm coming from on that angle?
I see where you're coming from but I don't think it really does imply they were aware of CVD enough to be snarky and wave a standard in their face. They probably just thought they'd give Apple some time instead of thinking 'I'll follow CVD here'.
