Apple will replace batteries for iPhone 5s and up, for $69-89 in the US. No issues with fakes or low quality. People who want to do some work themselves can buy replacement kits from reputable part suppliers for $29-59. Your problem only occurs if somebody wants to do the work themselves _and_ they think they can source the parts without assistance from a reputable part supplier.
