Here is my non-important opinion on the arguments you gave.
First of all "loadiine is not a tool which lets you download/unlock games" as for the first part, i agree, but for the second one, i totally don't, you have private versions with loading of non purchased dlc, which is in that category.
Then "it's not a tool to get things for free", well, the fact that you had to use a different patch for dlc loading that the private one you have for the sole purpose of not loading non purchased dlc show that the private version of the tool gets things for free, you just don't want it to be public.
next part, agree with you, not the loader's fault, and the current public dlc method does not allow for piracy (but the private one obviously does).
Next part, "unlocking is not the job of a loader" well, allow me to disagree, your private loader, i can tell for sure, does load not legally owned dlc, thus unlocking illegally content. also you claim that it's not a piracy tool....get real, i can bet most of you devs use it for that purpose, it IS meant to piracy, but you don't want to be the ones to publicly release that, it's fine, i can understand.
Also for the "project deletion or DMCA"....yeahhh, that's just not happening, i'm still waiting for any communication from nintendo for PastaCFW, which the WHOLE purpose was for piracy, so yeah, not happening.
And also, you should NOT be saying that if people have knowledge to do it not to release it, you should WANT others to release it, would give you much much more leeway in the future, since you wouldn't be the ones to "bring piracy to the console" (which to many people you already are, but that is not the matter discussed here...)
So all in all, it's not a matter of the tool not being designed for piracy, IT IS designed for piracy, you do use it for piracy with private versions, but you don't want to release it to public, and as i said, it's perfectly fine, your software, your decisions, but DO NOT tell that it's not it's purpose, as that is pure BS, you can say that you don't want to be publicly associated with piracy, that is totally fine with me and for some regards, respectable by me, but don't say that it's not what the tool is supposed to do when all the users use it for that.
On the other hand, i do userstand your stand point and do respect it, but damn, give us proper arguments next time, please
