> To me, it sounds like "modify and/or distribute" means it should be okay to both modify and then distribute the modified version.

In fact, and/or is exactly the way to specify that options can either be used together or separately. The FSF's claimed problem, you'll note, isn't that this language was ever held to restrict distributing modified versions, only that similar language was once argued by a party with a financial interest in the outcome to have that effect.

Which is a pretty flimsy basis to assert a problem. I'm sure you can find passages in the GPL that are "roughly the same" language to something that someone, somewhere, argued in a court case meant something that would be frightening if it was what the similar language in the GPL passage was actually treated as meaning under the law, but the fact that someone once argued that a similar piece of the language means something doesn't mean that the language that they argued about (and even less, the actual license language that it is "roughly the same as") has ever been or would ever be given that effect in court.

Ultimately I care more about avoiding the increased risk of the ISC license than about saving a few lines. It would be silly if trying to make my license statement a few insignificant lines shorter prevented someone from using my open-source code.

My point was that the argument that there is increased risk is based on a flimsy premise which could equally well be applied to just about anything; there's very few pieces of commonly used legal language where someone, somewhere hasn't at one time or another argued that something phrased in "roughly the same" manner means something that you'd want to avoid.

And my point is that even going through this legal reasoning is more work than just saying, "Fuck it, I'll use the MIT license."
