Update (and this belongs at the top, so you read it first):
Hi Alan. We don't have any way to block images based on their content, so no, we're not doing this. If an image on your site isn't loading via the CDN, please contact our support team at https://t.co/ANGtVS4PDJ with more details so they can take a look.

Glad to hear that Jetpack is not blocking anything with their CDN and kudos to them for their response!
After posting “I Stand with Ukraine (with the Ukrainian People),” I checked out the post, and it looked like this:
I changed the image size. No luck.
Then I thought about how I had Jetpack serve up my images from their CDN:
Turn “Speed up image load times” off (getting it from my server instead). Image shows:
Turn it back on, image disappears. Turn it off again, image returns.
So, if I serve it locally, no problem…
Is Jetpack blocking the Ukrainian flag on their CDN?
