Hehe. Yeah I meant per default, everything is copyrighted. So it’d fall back to being restricted and thus “not allowing anything”… If the wording doesn’t hold up… I’m not really in the position to judge this. Could be very well the case that once somebody touches it, it’s not “this” product anymore and it’s no longer covered. Or taking just parts of it is also not “this product”. Or a copy. I can imagine that something like that is the reason why other licenses go on and on talking about modified versions and copies etc… But I’m really not a lawyer and you’re right with being creative with things. I did not intend to be too negative 🤗

I think it’s the other way around, however… You need to word it so your users can enforce it against you even if you yourself become malicious. Otherwise you’re not really allowing them anything. And for that you’d need to word it so it doesn’t depend on your interpretation, but on theirs. And it’d need to hold up in court for them. So the language needs to be specific and with well-defined words. Every bit of vagueness it the user’s problem and limits/restricts them.

I thought the main problem was that it’s debatable whether you can enforce it. So it harms users and distributions because they can’t really rely on it.

But the liability would definitely be another issue. I think the law is different here in Europe, so the liability might already be included for my hobby tinkering per default and I don’t need to worry.

And something else is: I’d include trademark… force people to choose a different name for their project if they take my code so there is no confusion and people can’t upload versions with advertisements on some software store.

Uh, just don’t mistake it for a license. It’s funny and I like to put my stuff under WTFPL. But in recent times I feel it’s appropriate to point out that you sometimes don’t do your users a favor by being silly (if it’s useful code.)
