That's true, but having been around the BRZ community for almost a decade most of the engine problems boil down to a few things.
Endlessly beating on the cars, going forced induction, crappy tunes.

And excess RTV on many new ones. There was also the whole valve spring thing (the same problem impaced the Impreza to bring this back full circle).

There's actually not much Toyota in the Toyobarus, just the fuel injection system and drivetrain, and there are many surprisingly easy ways to wreck a stock FA20 or FA24. They're all specced for the thinnest oil they can get away with and will heat the oil to destruction after just a few minutes of hard use unless you add an oil cooler. The FA20 comes with an overly restrictive oil pickup, the FA24 comes with a revised one but it may come packed with bits of silicone. The stock crank pulley has a rubber damper in it that tends to fail catastrophically. They probably should've come with an oil pan baffle but didn't. The stock fuel basket's tendency to run dry in left turns doesn't help.
Then there are the ways you can wreck the engine with mods. Adding boost is a very high-risk endeavor. The stock bottom end will not survive putting out more than about 300ft-lbs. It also won't survive having a lightweight single-mass flywheel and undamped lightweight pulley attached at the same time. A stock FA20 is good for close to 8krpm (with high-flow pickup, otherwise avoid high revs due to oil pump cavitation) but if you go much past that, the stock oil pump will grenade itself.
Still some leftover 2022 Sparks with a 5MT:
