BitTorrent tracker iTS now blocks users running Windows 10 from using their website to access torrents because of the new operating system's privacy settings. iTS maintains that Windows 10 tracks "every action, email, conversation, video, picture, or anything else that you do on your computer." Microsoft shares the information it collects with an anti-piracy company.
Other BitTorrent trackers are considering following iTS's lead.
