Why has Yahoo removed all their cool stuff like Yahoo 360, Yahoo messenger and Yahoo games?

Different reasons Yahoo games were removed by Yahoo on May 13, 2013. That was almost 6 YEARS ago. I don't remember when Yahoo 360 was removed, but that was also probably 6 or more years ago when Yahoo was losing money and Yahoo was laying off employees, as much as 14% of the Sunnyvale staff bring laid off in April 2012 a month before Yahoo's 4th acting CEO in a year was forced to resign because he lied on his resume a out having a B.S. in computer science.

Yahoo then hired Marissa A. Mayer away from Google on 2012. In 2013 the disastrous purple format was introduced. Yahoo continued to lose money. The Yahoo stockholders an investors revolted in summer 2014. Yahoo sold off ALL of its stock over 4 days in September 2014 and put itself up for sale. AT&T and Verizon made offers. Yahoo accepted Verizon's offer and rejected AT&It's. Verizon took over Yahoo's Sunnyvale headquarters on June14, 2017.

Verizon Oath terminated Yahoo Messenger on July 17, 2018 because it was an outdated app.
