Rav Moshe Feinstein relates to our issue in Igrot Moshe OC vol.I, responsa #98 and #99 (pp. 159-160). Rav Moshe writes [in response to a question (#98) posed by Rav Aryeh Kaplan] that one who invites people who drive on Shabbat to participate in a minyan, transgresses the prohibition “Lifnei iveir lo titein mikhshol” (Do not place a stumbling block in front of the blind) because of his involvement in their Shabbat desecration. He goes a step further in responsum #99 and claims that besides transgressing lifnei iveir, one who invites another to do something that inevitably involves desecration of Shabbat is defined as a “meisit” (one who incites another to sin).
