1) FA20 is not engineered for stresses of forced induction, STI motors are.
2) Factory FI systems are typically better engineered than aftermarket add-on solutions.
3) Installer error can have expensive repercussions, vs. a car that rolls off the factory floor with FI.
4) People tend to cut costs and not employ fail-safe measures when installing aftermarket FI.
Risk vs. reward. If you go FI, just make sure you have the funding to rebuild a blown motor. If you don't, and you're satisfied with an incremental bump in power, go the NA route. You can really change how the car feels with just a few simple non-FI mods.
