Exaggeration !
Horizon Flyer vastly overstates the case against the Lycoming engine like any piece of machinery requires care and maintenance.
Nothing Horizon says is untrue but the chances of all the things to the same engine are minimal, I have yet to see a crankcase that has been properly crack tested fail in further service, likewise the internal components go through NDT to avoid failure in further service.
The biggest problem is low usage with internal corrosion being a killer of cam shafts & cylinders with low oil temp being the prime cause of the moisture that causes the corrosion. Lycoming do publish to avoid these problems.
