FWIW we've been rejecting posts coming from @yahoo.com addresses for a long time now, since DMARC was first introduced. We didn't get around to blocking other domains owned by Yahoo such as ymail.com or national yahoo subdomains, but I assume (without checking) that those will cause trouble too and we will have to block them out in order not to fill our queues with useless bounces.
Yes. The difference is they changed it from a soft fail to a hard reject, AIUI. From all of their domains (Kevin forwarded me the responses from Yahoo support). So the problem got worse, but it's the same basic one.
