Nope, they will let EVERYONE in, unlike Blizzard they don't have something in fine print that says *Subject to change.

You're fooling yourselves if you think server upkeep costs anything now days.
In 2010 when blizzard had 11.5 mil subs, it cost $136,986 per day for ALL servers in EU, US, Asia combined.
That's when they were making $172,500,000 a month from subs. chump change to them.
IDK how much it is now, but you can find it here
