You have me a bit mistaken here.
I indeed do not have a lot of time but I do have enough to be able to dedicate 2-3 hours a day depending on the day after work which I m willing to bet this is the category where the vast majority of players fall under (plus or minus one hour).
Wanting to also enjoy other games does not mean I do not have the desire to play WoW. It means that I enjoy it when I have the choice to either spend 1-2 hours each day on WoW and then 1-2 hours on another game and be able to keep up or spend 4 hours on WoW for 2 days straight and then spend the time also enjoying other games rather than "no other game allowed because you have to spend 3-4 hours a day to keep up with WoW".
You find it asinine that they would design a game around people who do not want to play it 24/7 and I find it asinine that they would design the game around the small % of people that have infinite free time on their hands.
Last time I read a survey around MMO players, the average player age was around 26 years old, and more than 50% of the sampled people were full time workers. Interesting to note that this was a few years back and this was a survey spanning multiple MMOs because I am also willing to bet that WoWs average age demographic this day and age is higher than other MMOs both due to the sub fee and due to the age of the game. Thus, the % of full time workers is likely to be even higher.
I therefore find it logical that they design the mandatory activities of the game in such a manner that you can complete them within a chill weekly timeframe, leaving you ample time to pursue non essential activities or enjoy other games. Calling DF WoD 2.0 is a bit disingenuine as we now have far more evergreen systems like M+ that we did not have in WoD.
