Blueprints, maybe, but conscripting company employees would certainly fall under the prohibition that it can't be "unreasonably burdensome".
Suppose you assemble/configure/sell gaming PCs, one of your customers is arrested, and the local police department is understaffed and technologically illiterate... Can the local deputy show up at your front door and force you to teach them how to find the recycle bin?
