We must have a legal framework to do this, because while the power is just a vote away, there are no rules for how to measure thresholds. Because of this, it becomes arbitrary, which is not how our legal system should work. The hard part is finding an unbiased economic framework for understanding conglomerates like Microsoft. I suspect that if we built such a thing it would necessarily take down more than the tech giants. The media conglomerates (Disney, Warner, etc...), and more importantly, the financial giants. You have hurricane-strength headwinds to make something like this happen. I'm not saying it shouldn't, I'm saying it's very difficult.
