In the following article, https://www.activisionblizzard.com/newsroom/2022/05/king-diversity-space-tool, Activion-Blizzard seems to admit that they abuse worker's passion by using tool made by engineers in their free time:
According to King Globalization Project Manager Jacqueline Chomatas, once MIT handed over the basic software, the team at King spent the last few years honing and developing it, mostly as a volunteer effort. People were spending their off-hours working on the tool, simply because they believed in its potential so much.
The article also is an obvious PR stunt to try to wash out the fact that there's been multiple allegation of an toxic working environment mired with sexism and discriminatory practices.
Especially following the last few weeks about their maneuvering personal around to deny them unions.
