I think this comes down to the old machlokis with regard to Kiruv:
With the intention of Kiruv, are you allowed (or even encouraged) to invite non-frum Yiden to your home for a Shabbos meal or Pesach Sedar knowing that they will drive and be violate Issurim?
How often does the food arrive a few minutes before Shabbos and you know that these non-frum delivery people are going back and traveling on Shabbos; but the Hechsher is tops, so enjoy.
