Tightly-Integrated Tech Stacks Did Worse Under GDPR: INSEAD Research

The headline-grabbing conclusion of this INSEAD study is that ecommerce companies with tightly-integrated tech stacks grew more slowly under GDPR than companies with loosely coupled stacks.  The academic jargon is nearly impenetrable but the authors seem to argue that tightly integrated stacks are harder to change, and this resulted in worse customer experience when GDPR enforcement began.  It’s intriguing if not entirely convincing.
