So many experts on German law and tort in here!
It's amazing how people can accuse the OP of greed.
And how many fall over themselves to defend a trillion dollar company.
Apple does not do most of its repairs. I have worked as a contractor providing labor for Apple. Computers going for repair go to vendors all over the world. Those damaged parts then go to other vendors that can sometimes solder them in a way that they can be used for other damaged computers that come in. Apple usually charges about $800 USD for these logic board level repairs.
When I personally had to send my 13" 2012 MBP in to Apple, I swapped the drive, installed a clean copy of OS X on it, and then put my own drive back in when it was back from repairs.
Unfortunately, Apple now uses non-standard SSD connectors, which makes privacy much more difficult with regard to repairs.
Other companies like Lenovo even offer to send back your original hard drive if one fails rather than do what Apple does which is to repurpose it.
When AppleCare asks for your password (which they do on all mail-in repairs), do not provide it.
Since it's now impossible to remove the drive and swap it out (well practically impossible), I would suggest backing it up and erasing it before giving it over to Apple, which is obviously not ideal. Of course this is impossible if the computer is not functioning at all, which is why having modular parts would be good.
Apple routinely asks for passwords, and they shouldn't.
You all are attacking the OP for what is standard operating procedure at Apple and which they should not be doing.
If you send a MacBook to Apple, it is not going to *Apple*. You will never know the name of the vendor and the subcontractor actually working on it.
This is not just about the value of the computer. It is about the distress, the inconvenience, and the terrible advice they give with regarding to safeguarding data and asking for passwords or to deactivate them. It goes back to them making over-engineered computers that require extensive repairs to replace simple parts. It also goes back to Apple not employing the people who work for them and sending out to third party vendors.
This is just one known example of contractors snooping through someone's phone and posting the pictures/videos online:
Apple paid a sizeable settlement after iPhone repair techs posted explicit photos of a young Oregon woman, according to legal documents uncovered by the Telegraph.

Remember that is just one known example.
Here is a person who suspected it:

I would never trust Apple with a repair because you don't actually know *who* is repairing your product unlike using an independent repair shop.
When people are bored, angry at the company they are contracted for, not even being paid minimum wage, and aren't even Apple certified techs (yes, that is correct: the people repairing computers at these vendors do not even receive Apple training or certification because they don't work for Apple), these things happen.
Some of you are demanding the OP be reasonable to Apple. Do you think Tim Cook got to where he is and where Apple is financially by playing ethically? They cut costs at every corner and demand the impossible from their vendors and then pretend to be surprised when there are issues.
