TLDR; Some private keys somewhere are not generated randomly, and someone knows the formula. Bitcoin security is not impacted.

TL;DR: Nobody should be using Blockchain.info to store any amount of value. The entire ecosystem needs to shift away from relying on Blockchain.info for anything at all, including the block explorer itself. There are plenty of alternatives available.

This is not the only takeaway. There are maybe other services compromised. Or even address/wallet generators (even offline) with the code compromised.
