I think we would both agree that iPhone 7 is DRM laden. However iFixit, who is quoted in the parent article and gives iPhone a repairability score of 7 of 10, seems to think there are some things which are repairable at the component level on an iPhone 7 even to a layman at home. https://www.ifixit.com/Device/iPhone_7
How does one interpret this? No glue allowed at all in any product or subassembly? Do you seriously believe any iPhone engineer would say a connector or screw was there "for the hell of it"? You claim a software check prevents a device from working. I'm sure their software engineer would claim the check ensures it works as advertised (or safely or whatever) because they don't know what you just did to it.
Your reply very clearly shows you have not thought through the consequences of your request.
The bare minimum would be to require an infinite warranty. So free, and with compensation to the customer for the repair time.
Don't want to deal with that? Get rid of the damn locks already.
