His point went clear over your head and into orbit, the Expansion was totally free, you got all zones, all content, all dungeons, all raids, everything for
free, to recoup the costs players got asked to buy earring slots, an item a heck of a lot cheaper than an Expansion and guess what? they cried and cried and cried, apparently getting an entire Expansion wasn't good enough, nope, no siree, they wanted it all, all for free.
This is why it's now buy this new Expansion, get everything, simple, it could have been a case of also getting this Expansion for free but the self entitled made their bed, now they get to sleep in it
Following on from that logic, WoW Devs must be eating lobster and caviar every night with the amount of money Blizzard makes from double and triple dipping it's players, take a look at this chart from 3 years ago:
Notice how it says 'Top 10 Online games by Free-to-play earnings'
Anyone like to explain how a Pay to play MMO with a sub can earn $213m from F2P transactions?
