Yes, but that doesn't mean you shouldn't listen to them. You listen to them and you evaluate their claims.

To be truly impartial I don't think you should even evaluate their claims directly. This allows them to focus the comparison on things they care about, not the things you care about. Instead you should decide what problems you need solving, and evaluate solutions to those problems against your own rubric.

“Listen” is being used in a non-literal way here, with the meaning “to accept as true”.

It seems to me that the original poster meant "listen" in the sense of "believe," not "listen" in the sense of "hear."

You are correct, I simply mean we should keep in mind that they are also selling something.

If you ask an AWS consultant what the best solution for your problem is, don't be surprised if the answer is AWS.

Humans lie

Companies exist to influence others.

What do you think anyone talking to the press or commenting on social media is up to?

Every company exists to get money; it is literally their lifeblood.

Not every human on social media or talking to the press is trying to influence others in a survival situation. Go touch grass.

Companies are organisations of people that have a common goal.

Yes to make money so they can provide a roof and food for their families.

But also other goals. To invent. To create. To provide goods and services.

People lie.
