It means they are suspect. I think its right to be wary of motives if they are involved in the very thing they aim to bring awareness too. Questions arise in my mind as to why they would do something like this in the first place.

Its been my experience that the general public doesn't seem to follow patterns and instead focus on which switch is toggled at any given moment for a company's ethical practices. This is the main reason why we are constantly gamed by orgs that have a big picture view of crowd psychology.

I don't trust them more because of this and maybe they've disclosed it for the wrong reasons, like not allowing a competitor to use it when they don't, but at the end of the day they did disclose a serious issue, and that's good for users.

I understand where you're coming from, by the way, but sometimes the worst person you know does the right thing and it's not fair to criticize them for doing it (you could say nothing, don't have to change your opinion about them, etc). We also don't want someone to go "if I'm bad no matter what I do, then might as well make some money with this" and sell the exploit.
