My two cents: Infosys had a poor culture because of one senior manager who made it impossible for SD Shibulal and Vishal Sikka to operate as CEO. That manager abused the whistle-blower apparatus to uproot as many as 20 senior managers. [1/2]
The investment was made to a non profit long ago. That was for public good. There was no valuation. As for Vishal, check what has he achieved after leaving Infy? If he was such a great visionary he would have a very very large AI co like Sam Altman.
