Yes, I should not have used the word dumping there as it's not in the same context as its usage upthread. I just meant they plowed all their profits into R&D and infrastructure growth, and as a result had very little or even negative taxable income. They operated at a loss, but it was contrived. They had revenue pouring in.
While I agree we want to incentivize investing in future capacity, I don't think we intend that incentive to be used to create monopolies. As with many things, what's good at small scales can be bad at huge scales.
The tax situation isnt what created monopolies. It was and is available to all.
It is unclear what is bad about it, as long as they provide a better or cheaper product than the competitor.
If they are ilegally preventing competition, then regulatory action should be swift. Otherwise, it is a win-win and the consumer is getting a better product than others could provide. This is the classic walmart scenario.
