Do I trust Google, MS, Apple to tell me the truth any more that I trust CNN, Fox, etc, to? Absolutely not. On the other hand, I expect corporate spin from the former, but I have a right to expect ZERO spin from the latter.
For me it's a difference in expectations. I expect a journalist to be fair and impartial. It rarely happens, but that is the way it should be. I expect a tech company to be fair and partial to its customers, but still do whatever it takes to sell their product.
