The Brussels Effect takes care of a lot of hardware changes for the better, for the world (think USB-C).
But for software, not so much.
Examples:
* Windows N (no media player stuff) and KN (no media player stuff, no messenger)
* Windows installed in the EEA (ability to disable / change start menu search with Bing, ability to remove Edge, ability to add widget providers)
* iOS with only allowing 3rd party app stores and 3rd party browser engines in the EEA.
* Google only allowing certain things when the phone is in the USA.
And it's gonna get worse with age verification. All of the sudden the manufacturers have even more data.
