Because they require these to work.

I can't say for sure, but I believe they already don't call home: this is also why building a solution to block them from "what if they started to call home" doesn't work.

If they don't call home, then the foreign interests wouldn't be getting the data, I think? If the concern is access to inferred logistics and crane telemetrics, then the solution would still seem to be removing access to the data or retrofitting new controls systems to the cranes, and not replacing the entire crane.

What if its wrapped in aluminium?:0

Just guessing that the software forces you to put in tracking information for every item. If it can't read it, you'll have to input the stuff manually. I bet they make that interface painful too.
