vague laws are put in place so that they can be used selectively to punish particular victims while letting friends through the nets
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.
There are degrees of vagueness, but laws generally attempt to avoid being vague with many definitions and strict construction. If a law is sufficiently vague it may be invalidated, or it is at least required to be interpreted to the benefit of the defendant under lenity.
Make it unambiguous that 100% of people are criminals, and all you have to do is control the prosecutor’s office.
This law seems to be in that category.
Frotz and Zork/Tristam Island and tons of Z3 machine games cna run on a pen, on a FPGA based display and even under a PostScript file where the interpreter was done in PostScript. Heck, with Subleq and EForth some Z3 interpreter can be coded to run the games on simple hardware made with high school/advanced trade electronics kits.
