I don't get your point.

What is written on the website of some company/organization/... when writing about itself, is what the respective company/organization/... wants you to believe about it. It should be trivial for you to recognize that what this company/organization/... wants you to believe about it can be very different from what you desire to find as truth about it.

It's like if I wrote: "aleph_minus_one is the greatest human that ever lived on earth." Do you now seriously believe that just because I wrote this about myself, it must be the truth?! :-)

Yes. They vote with their (lobby) money almost every day, unless you, who votes with a pencil, every four years.
