As others have pointed out, send DPA a polite message pointing out that
that clause makes it impossible for you to use his software in a
distribution that created with the explicit aim to get rid of systemd.
Politely ask if the license could be modified.

You might find some people are actually sensible ;-)

If the clause remains, the library should stay out of Devuan/main no
matter how badly you'd want to use it. Removing the offending clause or
relicensing (dual licensing?) to a Free Software license is the only
acceptable way to get this into Devuan/main.

A MIT or BSD-3-clause license would probably be most widely compatible.

Hope this helps,
