I actually totally agree with this. There's too much risk involved with scams disguised as legitimate services because the developers of said service couldn't be bothered to add 1 or 2 dns records.
Although there seems that there hasn't been any communication which is the bad thing here. However, nobody looks at those and sending detailed emails back seems like a good enough solution.
I don't know what "v=DMARC1; p=none;" is proving to anyone when DKIM and SPF are already aligned but sure whatever. Just wish they'd given some warning!
Maybe they should also work on what their users are sending as well.
