The source confirms Tallinn's involvement in Skype's development starting around 2003 and his role as a lead developer (implied by his work on the underlying FastTrack/Kazaa technology). However, the source does not explicitly identify him as a 'Co-founder' of Skype—it only says the P2P technology was 'repurposed to drive Skype.' The endDate of 2008 is unverifiable; the source only mentions he sold his shares in 2005 when eBay purchased Skype, but does not specify when his active involvement ended. The record is incomplete rather than contradicted.
