It makes sense to ask the government to cover your costs when you're doing something on a court order, and by god you aren't going to lowball it. On the other hand, it should hurt to participate in something like this, and a corporation of any significant size doesn't have a conscience to pain it (no matter what the feelings of the people animating it.) If the government reimburses companies for a generous estimate of the costs, they won't have to worry about the industry lobbying against this kind of coerced cooperation in domestic surveillance.
