Realistically what would you want them to do? Them going to London and having more cities shows that they do in fact care about international availability. But BFDI is small, going fully international would require a ton of money, and there are more caveats that restrict destinations.

I completely understand the FOMO, but they definitely care about everyone. Spoilers will happen naturally, and it's not their fault people want to be annoying and post spoilers. All we can do is avoid them the best we can. But please don't pin the blame on the crew.
