I don’t think there’s any simple catch-all answer in the general case. The license’s wording (which just forbids use “primarily intended for commercial advantage or monetary compensation”) is deliberately ambiguous to give the licensor leeway in assessing each case. The licensor’s intent is what matters, so if you’re unsure about whether a specific real-world case would be likely to qualify as “primarily intended for commercial advantage or monetary compensation,” just shoot me an e-mail at rob@intelligence.org and I can explicitly confirm for you whether the use jibes with MIRI’s intentions.
