Removing his lectures seems a bit extreme. It's their content, though. They do only mention "MIT OpenCourseWare and online MITx courses" though, so hopefully the lectures will stay up on YouTube. They really are excellent lectures.
That said, I've watched a good portion of Ramamurti Shankar's lectures from Open Yale courses [0]. They're pretty good, but perhaps not broken down as logically as the three courses of Lewin's.
There is also some really good lectures from Leonard Susskind's The Theoretical Minimum [1]. However, these are perhaps a step beyond the normal undergraduate lecture series.
