I would like to separate the questions about moral judgements about a company from the question of whether or not it is suitable as a sponsor. “Taking money from”, “advertising for” and “endorsing” a company are three related but distinct things and in my view these distinctions currently matter here.
And I understand that people who dislike military companies most likely will not want to have any advertising done for these. On the converse, this still leaves room for people who feel neutral or otherwise about these companies to still disagree with doing any sponsorships for them.
