The missing definition

Under any circumstances, I think it would be awkward to investigate wrongdoing before the definition and parameters of what constitutes it have been established.

Market size and segmentation, and even the distinctions between the five subject companies, are all unclear. At a minimum, they compete fiercely with each other.

Even the label “big tech” is arbitrary and probably misguided.

This might still just be a misunderstanding.
