Yeah, good call, but I honestly have no problem with that 1-star either. They can’t say “well we just opened the garbage conduit and pointed it at your face… we didn’t actually MAKE the garbage.” Those ads are part of their app experience, now. They published it, so they’re ’re responsible for it. If it sucks I give it a sucky rating.
Yep. There's no other way to maybe-convince them to get a different ad provider, because they're the ones that chose it (probably because it paid the most).
They did work with a bad ad network though so it's a valid enough reason to complain imo.
