the regional license thing is always been there just that they did not enforced until the last update.
In other words , they gave, then took away.
If I'd have had a "this will not work after x date" or a "warning, this update will remove the global licence" type message, I'd have planned around it and not been left without nav mid trip. Hardly the end of the world, I know, but very irritating nonetheless.
There seems to be general cconfusion within Nokia support about this too as it took them almost 2 days via a torturous "what SIM, remove reinsert, what phone, check with manufacturer for updates, here's the link to download, its in the store, where are you, what network are you on" set of questions.
Nokia support were themselves very much of the opinion that HERE Drive+ is available to non Lumia users until they checked deeper...
