I think you hear nothing about it because people have offered other explanations.

There are no any other explanations, only FTL one and weak attempts of opponents to misinform others about experiment details. The latter ones is futile, because experiment was reproduced by independent researchers with results even worse for relativists.

I have seen a paper on causality violation, that it can happen according to some test conducted where photons are reacting to something that hasn't happened yet.

Please share a link or doi if you have it, I like that fringe things a lot.

Our knowledge in the field is incredibly primitive

Our knowledge on quantum physics could be completely worng, like in a case with a theory of flogiston, that was completely wrong, but allowed to do a complex thermodynamic calculations that was perfectly accurate.

As for quantum computers, I could imagine some usage in cases where you have to deal with probabilities, since all quantum physics is about probabilities, but that niche in no case interfere with anything that advertised about quantum computing in MSM.
