The 300 stones has nothing to do with how much JP players dedicate to the game. Nor was it JP giving its players better treatment. The situation with the 300 stones was due to banners showing false rates, which, if you don’t know, is an incredibly serious matter when it comes to Japanese Gacha laws.

Naturally, Akatsuki quickly fixed this and refunded all the stones everyone used on the banner so they can try again with the actual rates, and then gave 300 for compensation as it was the biggest and most serious error they have ever made.
