By "more difficult" I mean "not worth their effort." I'm hoping to dissuade them from even trying, not because what I have to protect is particularly valuable, but because in principle I don't want them snooping on my stuff, *or* anyone else's either. I want the bar for them to do so to be high enough that they won't bother unless there is some plausible reason for them to do so.
Here is what my belief explains that yours does not: if their actions were not coerced, then the only other possible explanation is that they were rude, unhelpful, not in keeping with the general standards of open (or in this case semi-open) software in general, and burned every possible bridge back to the security community forever. There was no possible incentive for them to do this and every reason not to. The only reasonable alternative is that they were coerced, and the only entity likely to do so, and capable of getting away with it, would be some agency of the U.S. government.
