True, I believe (although AIUI yahoo.co.* except for yahoo.co.jp have
p=reject, jp is franchised, not managed by Yahoo!), but those not
branded "Yahoo!" have p=whatever-the-domain-wants.

No, I'm pretty sure this is an issue of brand management. Although
AFAIK only yahoo.com leaked, Yahoo! eventually imposed p=reject on all
yahoo.co.* domains as well (except in Japan, where AIUI Yahoo! Japan
has licensed the tech and the brand, but manages itself). I imagine
Yahoo! probably manages a large number of transactional domains where
p=reject is appropriate, as well as several domains where it's a
massive PIT Internet's A.
