You are right about that!!!!!!!!
Given enough age(mostly sun/dirt) poly straps snap. Replace them if improper maintenance(not treating for UV/dirt) results in them getting dry and brittle and becoming a snapper. A snapper is obvious to the most casual observer.
That said, how do you maintain straps should be next question. The answer is vigorous washing in clear water at least once a year with a final rinse in dilute 303. This process is more critical to the south than to the northern USA. The difference between "intense-sun-and-desert-dirt" and "lower-sun-angle and clear-flowing-rivers".
Or simply pay the price and buy NRS straps. Rarely if ever have I seen an NRS strap become a "snapper".
Or, retire your strap when is obviously a snapper and take it to DRE or your local source to have it rewebbed for a reasonable percentage of the price of new. The cam buckle is much more expensive than the webbing.
I used to sew my own straps but time is money and I have sometimes just asked and paid my local shoe repair to do the sewing when I pre-cut the webbing. I have miles of spooled webbing so that is easy.
I welcome feedback on this opinion.
