When you do read the lengthy material at https://www.fda.gov/emergency-preparedness-and-response/coro... note that the approvals are based on fighting the disease. Reducing transmission — at which the vaccines were clearly highly effective prior to Omicron — is one part of that but an even more important part is preventing severe outcomes. Even with Omicron, the vaccines are highly effective at keeping you out of the hospital and even better at keeping you out of the ICU.

Again, they were approved for prevention. The applications were for prevention. The FDA is trying to rewrite history, but if you look at the actual applications then you can verify what I'm saying is correct.
SARS-COV-2 is a transmissible virus that causes the disease COVID-19.
In the medical jargon, disease and its causality are separate concepts (and this bifurcation honestly makes sense... There are quite a few diseases where the treatment is to regulate symptoms without any hope of doing anything to modify the underlying active agent other than wait out the immune system to deal with it). It is entirely possible for a therapy to "prevent disease" without reducing the transmission of the underlying virus that causes the symptoms that make up a disease.
It is unfortunate that because of the conflation of these ideas in the layman terms space, people misinterpreted what the vaccine was cleared to do. But blaming doctors or the FDA for that is like blaming computer engineers when users turn off their computer and then don't understand that everything in volatile memory wasn't saved to disk. "Where's my spreadsheet go? It was in the computer's memory, it should be here."
Also, prevention of the disease would mean that people are asymptomatic and/or that they aren't getting COVID. Hospitals in many areas are publishing data showing majority of people there for COVID are vaxxed. So much for prevention of the disease.
If you were paying attention, note the difference between saying it will prevent all retransmission versus reducing it, which is what happened. Also, try to compare what actual medical experts said as opposed to the political entertainers whose talking points you're repeating. The actual medical experts were quite clear on this, and Biden has been pretty clear that breakthrough infections are possible — hence the interest in masks to prevent spread and vaccination to mitigate the damage for the people who we know statistically will catch it.
