Well I hope they trust their LLMs completely, because I'm sure Adobe is currently going over their source code with a very fine comb to build a case. And they have LLMs to help with comparing too.
If the code is in a completely different language, what can Adobe do it's not gonna be copyright infringement? Derived work if the algorithm is the same? But at that point it's math.
I guess they can always sue over infringed patents?
