And when we do "finally come to realise" that, what do you think will follow?
If this decision goes "against" Microsoft, et al, I think that what will follow will be a series of large multinational corporations splitting some of their operations and services into multiple individual national-level companies, rather than everything being directly owned by a single parent entity.
For the governments, it would reduce the ability of companies to "avoid" taxes, or other local laws, whenever it suited them.
For the corporations, they'd get a single, known, legal jurisdiction to deal with; and generally much smaller market variation to tailor their product to. They'd also, in theory, have more autonomy from "head office", and freedom to choose business partners (local laws permitting).
For the customer, we'd effectively get more competition between companies and legal jurisdictions; with the customer deciding which jurisdiction is best for them, and not the corporations deciding for everyone purely for their own financial gain.
I, for one, welcome our new federated corporate overlords.
