Google is not trying to act like Apple.
SD card access was restricted because of privacy and security issues.
Let's assume all apps can access all files on the SD card.
That means that all apps can access all unencrypted files, like your photos, possibly log files, and much more.
That's a possible privacy and/or security risk.
All apps still have access to their OWN directory on the SD card.
For instance the app NavFree can store maps on the SD card, but other apps can't look into that directory.
With big games, you can try to ask the developer to have the option to move data files to the SD card.
As far as I know, even with Lollipop it won't be possible to move apps2SD, unless you root.
What has changed, is that you can allow certain apps to have full read and write access to the SD card (that means, outside their own directory on the SD card).
As the link says:
"Simply put, this means that an app like Poweramp can now edit tags on the songs you have in the Music folder. Or a photo editor can save to the Pictures folder, and not just its own folder. Or a file manager can move files around on the SD card. All the developer needs to do is update the app with the new methods."
