Well, if the companies in question get a subsidy from their government aren't they able to lower the price of their products? Thus making it plausible that the companies would sell their products at or below the cost to manufacture them? I mean, if I was a company looking for some profit, selling something at way cheaper prices than my competitors because I just received some free money sounds like a great idea.
I don't know much about industry with regards to financial reporting and subsidization, but that seems to be the argument I hear the most. The companies aren't losing money, simply getting it from somewhere else.
