semantic decentralization (not just AWS owning thousands of data centers and having their own distributed interoperability problems), standards, and regulations.

These are super interesting problems. However, it seems like selection pressures, or just pure greed, attracts people to the "easiest" solution: pure domination. You don't need to care about any of these (well, you still do eventually, but in the minds of said people) if you just have pure utter control over every part of the stack.
