Well not only, there are still industry solutions relying on this infra, going "state actors in our data center are not a threat".....

From Signal Messenger of all places....

I remember one intel technology was pretty thoroughly tested and field proven, (and had significant memory constraints since almost everything happened on-chip as far as I remember) what came after (with similar AMD/IBM/ARM tech) was quite controversial as far as I remember. I think it was SGX 1 vs 2 or maybe Intel-TE that was marked tamper resistant, because everything happened on die, but I could misremember.

On the other hand: Reddit thread about SGX from 5 years ago. I think the talking point even back then was "state actors in our data center are not a concern".
