Yep, this looks like a blatant abuse of the DMCA by Mazda. Either Mazda is engaging in scummy behavior or they need better lawyers. Either way, it makes me want to never buy another Mazda.

That doesn't stop anybody. Just this morning Amazon sent out a wave of C&Ds because people were using their public APIs to access "proprietary data."

It reads to me like: "this app does the same thing as our app therefore they must have copied our code; there is no other possible explanation". Cool story, bro. I hope the developers will fight back but that takes lots of money.

So what? They have more money, they decide what is legal or not.
