In this particular case, you would emphasize the distinction between speech and general commercial activity. Citizens United says you can't prohibit political speech just because it was via a corporate entity or paid for with a lot of money. But the actual case was about an anti-Hillary Clinton movie. And subsequent applications of the law have concerned things like campaign advertising (e.g. all things that look like traditional political speech). In this case, we're dealing with a condition of employment. Even if we consider it "speech", it's commercial, not political in nature, which courts could use to distinguish from the Citizens United precedent.
