That would only be possible if interplanetary matter had a nonzero
charge density. However, if there were enough net charge arount the
Pioneer to decelerate it as much as we've seen, the charge would block
any radio signals between us and the Pioneer, so we wouldn't even know
it's decelerating...

I am saying that if the Pioneer had an electric charge, then it would influence particles around it more strongly than it would through mere mechanical collisions. ...
