The problem here is that the green cells mean "considered strong" and the yellow cells mean... something else. But among practitioners, SHA-2 is still very much considered strong.

I'm also not clear on what the chart claims is going on with RIPEMD-160.

Probably 80bit collision resistance would be my guess. But that's not a concern for applications that require preimages to attack (e.g. Bitcoin 1... keys).
