On what grounds would it be illegal though? Things don't become illegal just because you don't like them. They may become illegal just because the president doesn't like them, but I don't think you're him, and in the absence of that, there has to be a majority of Congress and most of them want a reason.
It's not illegal to run code on a device without informed consent to everything the code does. The CFAA may be excessively broad but it isn't that broad.
