Only if the app’s traffic is unencrypted, which is a an important caveat. In practice, I doubt that affects many.
Still, thank you for the correction. I was under the impression there was another small case in addition to Safari but wasn’t finding it so thought I misremembered.
And it is relevant in this case since it is plausible someone added a non-HTTPS feed URL as a feed and never updated it.
