Nuance is not always a good thing. This type of nuance doesn’t forward the discussion in any way and, in this case, muddies the waters and leads to some odd implications. Sure, we can say there is no objective source of truth and chastise the author for using that word, but the term objective in this case has meaning that the author is trying to articulate… most likely that there is some overtly unbiased information source, in opposition to the information sourced from the company which has obvious incentives.

Additionally, by stating that the CSB provides an ‘alternative source’ of truth, as a correction to an originally described objective one, you are (possibly inadvertently) claiming that the company is also providing a different source of truth, rhetorically raising the value of the information the company provides while lowering the value of the CSB information.

Don’t be the person who adds nuance for the sake of nuance.

Going this way we should ban the word "objective", because no knowledge can be objective, because you need a thinking subject to process raw data to create knowledge.

Going this way we'll risk to end up in a world, where there is no truth and no falsehoods. All we'll have is something in between. It would take just one small step to say that any two opinions are equal in their utility.

You know, it is like Kremlin propaganda targets idea of "independent media", pointing out that any media is not truly independent, it depends on someone or something. It gets its funding from somewhere, it is subject of some laws and of abuses of law. It needs to take into an account interests of sponsors and from those who wield power. The core message for Russians is: Kremlin propaganda can be bad, but no worse than anything else. Or it can be reworded as: anything is propaganda. Therefore you can relax and just watch news of state television, because you'll never know the truth no matter how hard you tried.

It seems to me, that you are going in the same rough direction by rejecting objectiveness.

That's technically true but underplays the extent to which company self-enforcement PR is malicious nonsense at odds with reality. Companies are amoral piles of money which will do anything to become larger piles of money, and will resolutely resist any interpretation of events which harms their narrow self-interest.
