I think we're talking past each other.

Of course you don't owe them anything. And the disclosure is a gift, unless you also use it for self-promotion, which is the usual compensation model aside from bounty programs.

But if you want to improve the ratio of reasonable-to-hostile responses, it's worth spending an extra couple minutes composing your presentation in the most digestible way. Also it's good for business.

If you're serious about helping to improve the net, or being a good netizen, you'll understand that recipients come in all shapes, and you have the best chance of achieving your goals if you make a small extra effort.

If you're at all worried that your report will evoke a hostile response, you always have the option of reporting it anonymously. I've done this, and it does work (vulnerability gets fixed).

Or if you just want to laugh at the colossal morons who don't take you as seriously as you believe you deserve, then sure whatever.
