What are the terms of the Flash EULA that you might violate while spinning up a VM to read something? You're not planning to copy it, publish it, etc, and since you're destroying the VM later you don't care about stability/etc -- outside of the reading event, you are not doing any actions with the product.

I'm genuinely curious. I can understand an argument from principle like RMS might use, but I am unsure what the difference is between agreeing on a VM and agreeing not-on-a-VM.

I'm really trying to see an edge case where doing it on a VM that you destroy later is in any way worse (or even different) than doing it on a laptop that you buy, use, and then later incinerate.
