Follow the money
IIRC, India (and Singapore, and few others) is one of the countries that the EU considers to *not* have adequate data safeguards in place for any company subject to GDPR to use as a data processor. You can imagine, that this puts a dampener on all that yummy outsourcing.

El Reg readers should be aware that if they are working for an EU company (data controller) that uses an external data processor (such as an Indian outsourcer), they need to tread extremely carefully. The GDPR has real teeth. You do not want to mess it up.
