So in essence they studied all of six (6) panels in a non-dusty region with a mild climate and without notable saline corrosion AND the article even mentions that most other studies are well in the 25-30 year range. Also the study clearly outlines that older silicone panels can't be compared against modern mass produced variants. Finally the study only examines modules that are still working, failed or removed systems are not in the dataset so you have heavy hidden distortion.
The sample size is extremely limited. Six systems are not at all robust enough for global conclusions. This popsci article of yours doesn't hold up to scrutiny and neither it nor the study are enough to make sweeping generalizations like declaring the common 25 year lifecycle a myth.
