FWIW, I don't consider it a "problem" at all (most definitely YMMV, of
course).  I think this is what DMARC *should* be used for.

My interpretation is that this is a particular author (a corporate
one) allowing her MTA to digitally sign "her" mail, and soliciting the
help of "email for those who can't implement Diffie-Hellman off the
top of their heads" email providers' MTAs in the effort to protect the
author's customers from 3rd party fraud.

I don't know what "paypal-inc.com" is for, so I can't speak to that
one.
