Let's see, you are lying to Apple to get parts you aren't entitled to, you are price gouging people for parts that aren't yours to price, you are denying legitimate repair customers who actually need replacements by depleting stock, should I continue?
„you are lying to Apple“ How so? You order a replacement part from Apple for a device that you own. What are you lying about?
„to get parts you aren’t entitled to“ I mean, that’s
your opinion. I have a different opinion, but the only opinion that
matters on this topic is the one from the Apple Support.
If Apple considers everyone entitled to such a replacement part who owns an iMac Pro, then that’s who’s entitled to such a replacement part. Based on this you’re absolutely ordering a product you’re „entitled“ to, no matter if you want to keep or sell it afterwards.
„You are price gouging people for parts that aren’t yours to price“ How are they not yours to price if you are the one selling them? If you make an eBay offer for these parts then you are absolutely in charge of the price you ask for it.
The market regulates itself here – you yourself can set a price that you consider the product to be worth it, and anyone who agrees with you on your value-proposition and wants to buy one can do that from you. Anyone who doesn’t agree with you on its value can simply not buy it – but neither do you have to charge the price for it that others consider worth it. I myself for example would love to get a space gray Magic Mouse but I don’t consider the asking price of 250+€ on eBay worth it – so I just don’t buy one and wait for better offers. It’s that simple.
„you are denying legitimate repair customers who actually need replacements by depleting stock“ If supplies are limited, then that’s entirely Apple’s responsibility to deal with, not your’s as the customer’s. You are not denying anyone repair service through this.
Also, your statement here is based on the assumption that you are any less of a „legitimate“ customer in this scenario, just because on what you intend to do with the product. You bought an iMac Pro and you bought a replacement part, and now they are both your property and yours to do with as you wish. If you use them yourself, let them sit on a trophy board, destroy them out of fun or sell them to others who might want them more than you do – that’s yours to decide. It doesn’t make you any less entitled to the purchase.
Look at it from an utilitaristic point of view: who actually
doesn’t profit of it? Apple profits of you doing it because they sell more parts and make more money. You profit from it because you sell the parts for a little (or a lot) more than they cost you. The one who buys the part from you is happy because he wants the part and agrees with your value-proposition – his only alternative besides these eBay offers is buying an entire iMac Pro for 5000+€ solely for its accessories which he most likely doesn’t want to do. Even the people who want to buy these space gray accessories but don’t agree with your price also indirectly profit off it because the more offers there are, the more the price is going to decrease in the long-term. You’re contributing to making these accessories more available for everyone.
„Should I continue?“ If you want to, feel free to, because you haven’t convinced me yet that there’s anything wrong with doing that, or that I should feel in the wrong for buying something off them; but I also think this is a degree-to-disagree argument. Your issues all seem to come from the fact that you believe it’s intrinsically bad to order a product with the intention to sell it to others, and that people not owning an iMac Pro are somehow not „deserving“ of space gray accessories, whereas I (aswell as the people who actually do this, or who buy these kind of offers) look at the benefit of everyone involved and are of the opinion that the market should just do its’ thing.
