If you want to get a neutral analysis on the whole Diablo Immortal situation, I highly recommend the video of Josh Strife Hayes. He is not an innate Diablo fan and do not rage out of nowhere because “my favorite franchise is ruined”.
People have very good reasons to be skeptical of whoever will be offered by the in-game shop of OW2. Especially when you remember that Candy Crush is still responsible for most of the profit of ABK, and rely a lot in predatory MTX.
I remember that quote, I think it was around the first anniversary.
It’s really sad when you remember how much of a hit OW1 was at release and how Blizzard dropped the ball hard by bad management choices in general. People like to blame balance, but to be honest, most players don’t give a 
about balance, as long as it’s not egregious unbalanced. If you can pick any hero and have fun playing them, the game will survive.
It was entirely on management decisions. Things like prioritizing OWL viewership and merchandising at the cost of the casual side of the game.
I was 97.5% sure that the main reason to push the title change to “Overwatch 2” was to get away with Jeff Kaplan’s promise that all new heroes and maps would be free for all players of “Overwatch”. Thanks for the final push to change that value to 100%.
