That is not quite accurate. There are several bypass lube oil filtration systems available from highly reputable manufacturers and some of them are standard or optional equipment on engines direct from the manufacturer.

I don't have a photo to insert here at the moment but will take a couple on a boat later today that has 2 spinner type bypass filters installed on each engine.

If you want to start learning a bit about lube oil filtration, Cummins published an excellent guide:
