Limited number of disk bays? ;)
That would be the only reason. The cost of replacing existing 2TB
drives with 4TB drives seems pretty high. Performace would only go
down, and if the physical block size increases, then storage efficiency
would decrease. Disk bays are not necessarily all that expensive as
long as there is a place nearby to put it.
An existing disk chassis could be replaced with one which supports more
slots and the existing drives re-used as long as they are physically
compatible with the new chassis.

or just they need a lot of capacity for e.g. video or audio media. The
modest loss of performance would go roughly unnoticed. (home storage,
for instance)
