I think people are "acting like" it's scientific data about a vaccine of interest to the public.
Are you suggesting the data is unreliable or falsified? If so, and you have a basis for that, please cite.
Otherwise, it's difficult to understand why you're implying people shouldn't be interested in this information.
Why should they lie? If their data had something different to their press release, lying and then getting caught (e.g. by a whistleblower) would damage their reputation. If their data shows it's bad, as responsible scientists why shouldn't they come out with the truth to protect the general public, and say "We'll continue work on the Omicron-specific vaccine.".
Unless you think their main motive is to boost their stock price in the short term. That kind of thinking should be reserved for people dealing with the blockhain-ponzi schemes.

Phizer holds single largest criminal fine in human history at 1.3$ Billion USD (to my knowledge). They have many reasons to lie; while I'm not suggesting they are (I have no idea how I would determine truth from falsehood in the realm of scientific information) it's quite ignorant to make the statement "Why would they lie". They would lie because it's something innate to humans and Phizer is no exception. They stand to make ludicrous amounts of money if boosters become mandated - now boosters may ultimately be the best option for the protection of human life! But this doesn't mean we shouldn't be incredibly skeptical of every word that comes from this organization.
While I am fully vaccinated (ironically with 2x Phizer), I am and will remain hesitant at accepting information provided by pharmaceutical companies at face value until the day I'm dead.
Not to say they did commit any such errors here. Perhaps all such studies conducted by Pfizer are truly earnest and valid/replicable, I certainly hope they are. But it's perfectly reasonable to be skeptical of an organization publishing new science when that organization stands to profit greatly from the results. You may call that libertarian (though I'm frankly not sure how), I'd call it just due diligence.
