> shilling your product

I'm not sure that a plug/PSA about a government program really counts as "shilling your product", we're talking about a program that was enacted by the congress and signed into law by the president, at a minimum it's totally distinct from plugging a product that you own or profit from.

The inverse only works when you are a public figure with greater power/sway than those who enforce rules, ToS, standards et cetera, or if you have an insider track with those who enforce the rules who can elevate you above them (the rules), ignore them, or give you a free pass (ie you are friends with a high up employee at twitter).
