They might have proprietary encryption/ECC/rowhammer solutions, etc.

In fact, if you look at the design of SGX for servers...Intel can use multiple encryption algorithms for the memory (upto 16). I'm sure that is there to accommodate both cloud folks with different preferred algorithms.

More broadly speaking, if I was a cloud vendor, I'd want full end-to-end control to enable various system optimizations.
