re: How can one abuse "Unlimited PTO"?

Most places use this as “get your work done and you can use your PTO”. But it makes it difficult to schedule PTO and use it - the work never stops. Most companies you set PTO and people understand the work with falter for a bit. With the “unlimited PTO”, it’s the opposite, you can never justify getting behind on work while out

It’s probably a lot better used as taking bits of time off every day or every week, but less effective for taking larger chunks like a week or more
