Study shows blu ray discs last only about 10 to 20 years.

What we have here is a writer that was too lazy to cite his source or read anything. I found the "study" and it has nothing to do with the type of discs that PS5 games are.

The longevity of recordable compact discs (CD-Rs), recordable digital versatile discs (DVD±Rs)^{Endnote 1} and recordable Blu-rays (BD-Rs) is uncertain, leading to a widespread lack of trust by libraries and archives. Research studies, anecdotal information and manufacturers’ literature suggest that the lifetime of recordable optical discs can range from a couple of years to more than 200 years. This Note explores several of the factors that affect whether a disc will fail within a short period or will continue to perform well for many years.

A BD-R is a recordable Blu-Ray disk. It uses a chemical process to make pits and valleys in a Blu-Ray. 

A BD-Rom is a disc that is pressed at a factory.

They sound similar but are two very different things. Recordable CDs and DVDs are notorious for degrading quickly. Recordable Blu-Rays are just as bad, because they work the same faulty way. This is why people lost their minds when Limited Run simply used a CD-R for many of their disc-based releases instead of pressing the discs. 

TL/DR: Ignorant Game-Rant writer doesn't know the difference between a burner disk and a pressed disk. 

P.S. There has been no study on the long term stability of Blu-Ray disks. CDs are proven to last 70-100 years when stored at 70F and 50% Humidity.
