While there have been legal anti tampering requirements both in EU and US legislation, it is now being policed more. So manufacturers are legally required to take measures to protect their ECUs from being able to be reprogrammed.
Dieselgate was probably a kickstart for government awareness on this issue, and EPA/EU are now cracking down much harder on this.
And manufacturers warranty claim departements have a lot of problems today with people trying to get refunds on their tuned cars. Locking the DME even better will probably mean less investigative work for them, meaning money saved.
So both legal requirements as well as protecting the brand/image and liability are the main driving factors behind this.
