I purchased a phone in a European country without an official Apple Store, so I bought it from a "Premium Authorized Apple Retailer." After one year, the phone broke. While in a different country, I visited an Apple Store to have it repaired under warranty. However, they informed me that I needed to return to the original store where I purchased it to activate the warranty.
My experience with Apple doesn't sound so different from yours.
The belief that all mobile devices are this locked down is Apple's greatest trick.
I don't even think it is premeditated by the Company's leadership. But the users and ecosystem evolved in a way where this level of fandom and narrative are great for them.
