I didn't notice anything about closing the loopholes, just that they're making 11 Pro work like 11 Home. At the end of the day, forcing MS account use at the setup stage will always have a flaw in because MS has to leave a fallback option in for any network device that Win11 doesn't by default have a driver for.
I suppose they could stick in a prompt into the setup routine similar to the storage drivers prompt, but for network drivers. Though that would rely on network device manufacturers producing a driver that can be installed in that way, whereas some manufacturers produce a driver that's compressed into the install program. I suppose if they added the 'add network driver' functionality they'd then have to follow it up with full network configuration functionality and VPN connectivity though in order to cater for pretty much every networking scenario. As I said in a previous post though, I think this is about MS making peoples' lives sufficiently awkward so people just 'go with the flow', likely at minimal expense for MS.
I'm not sure what's with
@Zoozuu 's NSA fixation. I'm personally a lot more concerned with corporations spying as selling personal data for profit has been a thing for some time now. Sure, the UK government probably does spy on me a bit, but without a profit angle there's got to be a practical limit on the sheer amount of data theoretically gathered by a government.
