Dantoich was hardly a trusted member of the Iron warriors inner circle was he. Yet he was shuffled off to some garrison duty on a backwater planet. The Lion did the same thing to Luther and I am sure many other primarchs thought they same way. Give the troublemakers some sort of sinecure of a job but then those troublemakers would resent this and have all the more reason to stay loyal to the Emperor.

Plus there is the fact that warp travel is unrelaible so many chapters may have been out of contact for years before coming back to a changed galaxy. How much which side they would ahve chosen. Also not all traitor primarchs purged their legions. Magnus certainly didnt and the Night lords did not bother either.
