Mmm... Okay. I'm not going to argue over that as I don't want to lose my time proving and explaining to the least detail something that I didn't even bring up (and that I'm sure that you'll still tell me to look once again, after that). So you win, I don't care. However...
Should it really matter to us if SE as a whole needs more money? No, bear with me before you click "reply". This game, as in ARR, is financially successful and everyone knows it. It's even funding other parts of the company, so the money seems to be flowing. If SE is having problems with other projects they should try to get/save money by other means, maybe waiting until they get back more money before they open up more projects, or maybe making better games (and ports) or improving them. That way maybe people will invest more in the company, as seen in how a lot of us invested in ARR after they had the balls to do what not many others did before: redoing the game to improve it.
Now you can argue that they are not a charity, and blahblahblah, but I think that it's clear as water that ARR worked because many people (including myself) got attracted by the good faith of the company (something that was hard to see nowadays) and the quality of the "new" product. If they now try to change any of these, they're just shooting themselves in the foot. The aren't just alienating or directly losing many of ARR's customers, but also potential sales for other of their products that people might have gotten simply to support them, as it was happening until now. In other words, I see that as a financial suicide for them to take the "EA/ActiVision Route", specially if they "really" needed the money so hard.
TL;DR: ARR was successful "as is" and it seems that it was able to rescue the company from the hole that it was in. There was no need to change the status quo with a chance of alienating a big chunk of your playerbase and scaring away other potential customers with something as controversial as a cash shop, instead of just keep doing what they have been doing since 1.x's disaster. Haste makes waste.
