I think this is the least bad explanation, some explanations are that
copper may not be available, but that doesn't explain preference. Nor
do I think wattage/heat explains preference, as it's hosted, so
customers probably shouldn't care. Latency could very well explain
preference, but it seems doubtful, when hardware is so underspecified,
surely if you are talking in single microseconds or nanoseconds
budget, the actual hardware becomes very important, so i think lack of
specificity there implies it's not about latency.

I don't think you are going to get a single answer that has an overwhelming majority of support for fibre. Use-cases are very different, and what you will see in the field is some statistically insignificant representation of each of the reasons given.

By and large, I can say the bulk of servers are cabled with copper, which would make fibre niche if you took a global view. On that basis, squabbling over the reason is inconsequential.
