Supporting Israel
Your question has already been answered in the thread that you referenced above. Just to reiterate, most businesses are for-profit entities that are answerable to their shareholders. Generally they do not outright support any party in a given conflict. Unless there is objective evidence that a company supports an oppressor, there is no harm in buying their products or services. As Muslims we should also avoid speculations and conspiracy theories. However, it is each consumer’s individual right whether or not to buy from a particular business and we should respect that right.
