Why isn't every advertising/marketing data broker in jail for "jigsaw identification"?
Note the important bit here is in a criminal trial. Murray is going to prison because he was found guilty of actions which threatened to cause a mistrial in a criminal case, not because he was deanonymizing advertising/marketing data.
It's VERY convenient for those in power to selectively apply laws like this, and overall bad for society. But like most cases, as long as it isn't too blatant, it doesn't rise to the level of common outrage.
It got bad enough in the past to make the top of the stack of 'stuff to fix in v2' here.
The constitution though is just words on paper if people don't follow it day to day, and you can see examples of steady erosion from it (gag orders, national security orders, etc.)
