What is the ruling on dealing with an online food delivery website that displays advertisements for a telecommunications company known for its support of groups that attack the Mother of Believers?

Islam has permitted Muslims to engage in buying and selling with the immoral (fussaq), innovators (mubtadi'ah), and disbelievers (kuffar), provided that it is not in a prohibited matter. Al-Hafiz Ibn Hajar transmitted the permissibility of dealing with disbelievers in matters where the item of transaction itself is not definitively prohibited, and that the Prophet, peace and blessings be upon him, dealt with the Jews, and he passed away while his shield was mortgaged with a Jew. However, if Muslims see that boycotting the goods of an entity that supports people of falsehood or promotes those who transgress against the Companions serves a legitimate Islamic interest, then they are permitted to do so.
