All laws are vague and interpreted, and in common law (as in the UK and US) interpreted based on precedent rather than the specific text of the original law.

If people with power over you want to "selectively punish you" they don't need new laws.

And if you want perfectly proscriptive, defined laws in all situations with no "human interpretation" you're in the wrong universe, and may as well be shouting at clouds. The world, and especially human society and interactions, just doesn't follow strict definitions like that.

Vague laws are not required for selective enforcement. You can have strictly defined laws result in selective enforcement through law enforcement and prosecutorial discretion.

until you root out their friends and maliciously develop app stores for their products, then install them multiple billions of times on a docker and let them rack up charges ;) doom can run on -anything-
