It's not about religion, it's about trust and keeping promises. Like it or not, the default understanding in a marital relationship in many places in the world is monogamy. Some people, of course, engage in other practices, after an explicit discussion, and agreement and understanding. But presumably Huang's wife believed she and her husband were in a monogamous relationship, and trusted Huang to keep it that way. That's the issue; religion is irrelevant. (And different religious practices have different things to say about monogamy vs. polyamory, and atheists decide for themselves if they want to be monogamists or polyamorists; religion need not be involved at all.)

But regardless, I think his infidelity is not his employees' business; IMO it's weird to bring it up in this way. The bit about his affair partner possibly(?) being a spy is the thing that actually matters to NVIDIA and NVIDIA employees, but he only dedicates a few sentences to it.
