I get what you are trying to convey. I disagree but there is no problem in that. However: where does Apple state that their products may stop working if repaired with different components? (Honest question, I have tried to find it).
> Service Exclusions and Diagnostic Fee. Apple may charge you a diagnostic fee (including shipping charges) as described in the Country Variation table, below (“Diagnostic Fee”), if Apple inspects your product and determines that (i) your product does not require service, (ii) your product has failed due to or has incompatibilities with software or data residing or recorded on your product (iii) service is required due to the failure of parts that are neither supplied by Apple nor Apple-branded, (iii) additional labor or parts are required that were not specified in the original estimated charges and you do not agree to authorize service based on Apple’s revised estimated charges, or (iv) service cannot be performed because the serial number has been altered, defaced or removed or the product has failed due to accident, abuse, liquid spill or submersion, neglect, misuse (including faulty installation, repair, or maintenance by anyone other than Apple or an Apple Authorized Service Provider), unauthorized modification, extreme environment (including extreme temperature or humidity), extreme physical or electrical stress or interference, fluctuation or surges of electrical power, lightning, static electricity, fire, acts of God or other external causes (“Service Exclusions”). Apple will return your product to you without servicing it and may charge you the Diagnostic Fee.
This is from Apple's Repair Terms and Conditions: https://www.apple.com/legal/sales-support/terms/repair/gener.... It doesn't say that the product will stop working, but it does say that Apple isn't responsible for fixing it if it goes wrong. I'm not sure if that could be extended to them not having to support your third party component in software, though.
