Reminder: no employer that forces you to compromise your ethics and aesthetics by requiring you to run MS Windows is worthy of your talents.

If you need that job, then stick with it, but know that you have every right to feel aggrieved and unvalued (and to question both the competence and motives of those making decisions in the business), and that you should feel justified in jumping ship for a better opportunity that respects your intelligence & agency at the first opportunity.
