Lightning cables that aren't MFi certified are still widely used. See their presence is gas stations and other stores nationwide. Lots of "MFi certified" cables online are likely fake. Who knows?

USB Type-C can deliver enough power to seriously damage your $1000 MacBook if the cable/adapter is designed poorly. There is a certification process, but most products on the market are still below-par. Below I will link a list. Guess what, those "bad" products are still bought en masse.

This week, I discovered that pretty much all the water filters that are popular for the type I'm looking for aren't even certified to filter out harmful materials. NSF 53 certification exists, but it looks like the market didn't do any research into it and trusted NSF 42, which was touted but is a much less strict standard, filtering out odor and taste (important in its own way). Theoretically, these filters could be passing on lead and asbestos.

Your solution _might_ work for a _part_ of the market, but it is almost guaranteed that there will still exist a significant (if not majority) part of the market, that doesn't care about certification/prefers the cheaper product.
