Why does Fujifilm make such terrible cameras and lenses?

I borrowed my sister's new X-T2 and a few primes and every picture is a chromatic abomonation, has shit for brains rendering, and terrible ISO performance.

Aren't they an early adopter of mirrorless? How do they make such garbage, do they even bother with R&D? My Sony a6000 is light years ahead of their trash with the kit lens.

This shit was built for numales and girls with problem glasses.
