  And they don't even need it to be perfect: a robot that
implements the relevant browser APIs, while possible, /will/
be costlier to run and maintain, thus reducing the profits of
the robot operators, in turn disincentivizing them.
  Even if that doesn't solve the problem altogether, it will
still likely result in less load for their servers.
  Not that it invalidates any other reasons they might want to
require Javascript / APIs regardless, mind you.

A bot only needs to be able to send the correct data to the server. how difficult that is obviously depends on the details of the Javascript's interactions with the server, but frequent interactions themselves create a higher server load.
One example would be the mouse-movement based human detection. If the script just sends a yes/no message to the server, then the bot doesn't need to try to emulate a human at all.
