What box? Clippy already has internet access. Connecting it to the human financial system means clip-production capabilities will, sooner or later, become a matter of public record, which is considerably easier to monitor for imminent 'foom' than, say, encouraging the establishment of smelters and rep-raps in a Jonestown-style compound.

As for hostility, clip-maximization and willingness to negotiate don't seem too bad compared to the actual humans who think Jesus won't come back until the last tree has been burned, and are willing to abuse positions of political power to make sure that happens sooner rather than later.
