You can't prove a negative
*blinks*
You are calling me the "dumbass", here? 😅 Both logic and philosophy say this perspective is wrong, and also, funnily enough, if this were true (as in, it's not possible to proof a negative assertion in a burden-of-proof scenario) then that very claim could not be proven either? Because "You cannot prove a negative" is, in itself, a negative assertion.
Luckily for us this is of course wrong, and you can prove a negative. Especially in matters of fact, since you could find a list of current filings of Microsoft and hence show that no, of all their ongoing lawsuits, there are none that are targetting developers (which is not the case, it was easy enough to find two cases without digging any deeper).
And I mean, this doesn't do shit to exhonorate Nintendo here, but let's not pretend Microsoft and Sony aren't constantly running hundreds of legal cases and multiple will be targetting developers of all sizes. They're just avoiding big press about most of them.
You can just admit you were wrong, you know? Both about current legal cases and about how how proofs of negative claims are viewed in mathmatics particularly logic, and in philosophy. That's okay. Sometimes we are wrong, and we learn from accepting that.
I don't disagree Nintendo is a shithole company, after all. Just take it as a learning experience: More than one company can be shite at the same time.
