I hope you are being facetious. Many forum members here including myself are more than qualified to replace one of these batteries. But we do not qualify as an approved service center or oem.
Basically this is a move by Apple to rip off the customers since they will have no option to replace the battery themselves without exorbitant fees at third party repair centers since Apple would consider the MacBook
vintage in five years. This also rules out the option of getting a cheap third party battery via eBay which usually run half the price of brick and mortar stores. Adding this screw seems more an attempt to force customers into buying a new Macbook after five years. Though for most uses it the hardware will likely still be more than powerful enough.
I guess we will just wait until some foreign manufacturer starts making these screwdrivers and they make there way around the world.
