As a genre? I would say no. Cyberpunk is usually described as a capitalist dystopia in which a handful of companies supersede government powers and wage wars against each other beyond the concepts of national borders. In addition, cybernetic enhancements become commonplace, as a way for companies to extract more value from their workers. Cyberpunk stories usually are about groups rebelling against the system through organized crime, who ultimately fail to escape the underlying system of capitalism, doomed to repeat history time and time again.

HL2 falls in none of the genre stereotypes. While it is dystopian, it’s not capitalist, so it’s not “punk” and it isn’t “cyber” either because of a lack of commonplace cybernetics.

Additionally:

• while the food will taste the same, in most cases the mouth feel is so horrendously bad it will be inedible
• rehydration of most foods is very hard to impossible, limiting it’s uses even more
• if you put more than one kind of food in a batch, the chance of error in the process increase dramatically, because all food needs different amounts of time to dry

I’m pretty sure the only actual use cases are berries and fruits. But those can all just be dehydrated normally or made into jam, so there is little to no purpose for a freeze dryer, except playing around with foods, which is not worth the price
