OpenBitTorrent's initiative to provide a free, stable service with no ties to indexing sites or even hosting torrent files has been a public success and it has spawned several copies with almost identical services.
OpenBitTorrent has been suspected of being a part of, or a side project of, The Pirate Bay, because it was observed early on that both sites used the same trackers.
[1] The OpenBitTorrent project has countered by stating that the sites merely shared a tracker cluster operated by DCP Networks and Fredrik Neij during a startup period (February through August 2009).
[3] From 16 July to 2 August 2012, OpenBitTorrent went offline protesting the lack of adoption of a protocol improvement by the makers of uTorrent, that was proposed by Pirate Bay co-founder Fredrik Neij.
As a result of the protest, many people had trouble downloading files on BitTorrent.
