When they were tired about seeing their patches rejected from the mainstream kernel, they decided to try a different approach, and that approach is LXC. In other words, LXC is a reimplementation of OpenVZ concepts by almost the same team.
LXC is actually more secure than OpenVZ, if only because it went through more scrutiny than OpenVZ.
