In 2007, Omidyar invested in Maui Land & Pineapple, which was subsequently accused of being part of the largest human trafficking operation ever busted by US federal officials.
Between 2011-2013, Omidyar Network co-funded with USAIS regime-change groups in Ukraine that organized the 2014 Maidan revolution. In India, the head of Omidyar Network’s operation, Jayant Sinha, concurrently worked for the far-right BJP leader Narendra Modi helping him take power in 2014, after which Modi appointed the Omidyar Network partner as his junior finance minister.
Omidyar was investigates by Congress and sued for secretly “spinning stocks” — insider trading on IPOs — with Goldman Sachs. Omidyar was also accused by Craigslist and a Delaware judge of stealing the "secret sauce of Craigslist's success” and passing those secrets to eBay in violation of contracts, fiduciary duties and securities laws.
