I know of few to no services that you pay for that you can download the current version without an "active license". generally since you have to sign in to the launcher, its going to do a version check and see if you qualify for the current release software. no subscription active on your login, means no update.

if they did allow it then the OP would be mad that they cant start the game without a sub. basically, the concept that business follows is "if you really want to use the software, you want to have the latest version, thank you for paying..."
