Hope it's not optional, either, as the option not installed in MH370 that made investigators rely on dataless pings to dig out locations.
They may be talking about that amount of data over a year or more. If it's 200Gbytes over 2000 hours of flight, that would be 100MBps - impressive, but not prohibitive.
And it is optional.
