In light of how the company acts for example by taking down bounties without notice, I change direction in this answer slightly. My tolerance for suffering marketing speak consisting of half-truths (or "lies" or dishonest statements) like this one is actually not as high as I thought and I think now it would be better to rephrase or remove it. The only problem is that the company would have to do it. I doubt they will.
While I agree that the statements are somewhat misleading and not completely true, they are within the realm of the usual marketing speak one gets from every company. Such statements should always be taken with a good portion of skepticism. I usually just filter these messages out mentally and ignore them or adapt them.
Want some other examples: "Don't be evil" (Link), "Give people the power to build community and bring the world closer together." (Link), "We believe technology can and should be a force for good and that meaningful innovation can and will contribute to a brighter world in big and small ways." (Link)
The cases here are not better or worse. Don't only look on StackOverflow.com for information about it. A neutral description of what it really is may for example be found on Wikipedia (citing from it: "privately held website ... platform for users to ask and answer questions").
This is the site of the company and they can clearly publish information on it that's true or not so true. It's up to their discretion to decide what it should be.
I don't care because as I said I anyway filter or adapt marketing speak out.
