Anyone else want to be petty?

So I know when its not my place to something so I bite my tongue. BUT none of my husband's family, except one person came to the wedding because of covid. Most of them couldn't travel or get the time off, completely understood. But there is a couple of his cousins that couldn't come because his aunt threatened to kick them out if they came because of covid and needing to be cautious. Ok fine you can't help that. And then I see them posting pics at a GIANT event without masks on and no social distancing. Pisses me off so much for my husband that his aunt would be so awful to not allow the grown adult cousins who live at home to come to our smaller wedding with precautions but truly don't give a dang and just wanted to be hurtful towards him. GRRR. I won't say anything but wish I could! Anyone else have something they really want to be petty about but can't and need to let it out?!
