There are two issues with this.
First, its monetization of your gaming despite already paying a heft cost for the equipment. The reason to do this is so they can monitor your gaming habits, record the data and sell it on.
If they want to do that, then provide the equipment for free, don't charge people to buy stuff, then put use barriers in place so you can continue to profit from them.
Second is the nature of facebook. They ban accounts all the time, often for little reason, and often for political views.
I may not agree with those views, but in what world is it acceptable to potentially lose access to equipment you own, and games you've bought, because an algorithm at facebook HQ decides someone is saying something they shouldn't, entirely unrelated to their gaming at all?
Its not just facebook and oculus, this idea that despite paying fortunes for hardware, someone else still has control of whether you can use it or not is anti-consumer and patently ridiculous.
