I own zero Apple laptops, desktops, watches or subscriptions, and one low spec. 2016 iPhone bought second hand. That's hardly being a prisoner or being ruthlessly exploited, is it?
If you hate Disney's Frozen because you've seen it so many times, but you watch it with your daughter because she likes Frozen, does that mean you like Frozen because you're doing the same thing that people who like it are doing? No; people's motivation for the same thing can be different. People can do thing they disapprove of, for reasons other than approving of thing.
But as far as the market is concerned, if one has a choice and exercises it, they liked the product better than the alternatives. Nobody on the Apple galley was ever really forced to be there.
Even ten seconds thought should show you the problems with what you are saying. Even if you take it on aggregate, a million people buying Apple over Dell means Apple is doing something to attract money - it still doesn't necessarily mean people like Apple more, it could be that Apple are lobbying congress to require Apple for schools, or Apple offering employers a massive discount, or Dell having supply chain issues so the vote is really about availability not technical preference, or etc.
As far as the market is concerned, if prisoners like rotting food more than starving then they "like (and approve of) rotting food" in general. People understand more than just pricing signals and can see the problems with that reasoning. At least, I can. In a similar way that the playground challenge "would you rather (horrible-thing A) or (horrible-thing B)?" is hilarious because whichever you pick, it means you actually like horrible-thing, haha ha! This reasoning is "the market is a good judge of character and if it has judged you, then you must have that character". Another option is "the market works on very few signals, most of them monetary, and that makes it a poor judge of character and motivation and other higher human concepts".
Another comparison is the web adverts which reason "if you bought a lawnmower then you will want to see adverts for lawnmowers because we have strong evidence that you are interested in lawnmowers" - as we warn about markets, past performance is no guarantee of future interest in lawnmowers. It could mean you are a lawnmower enthusiast, but it could mean you are disinterested in mowers and but have a lawn and an obligation to mow it, it could mean you choose whichever is in stock at the closest store which is no vote about the product and only a vote about your local store's stock levels. It doesn't mean that if you bought a lawnmower instead of a private jet that's because you like FloorGoo lawnmower F6240h PowerMow+ with leaf-eviscerator extension more, only that you can't afford a private jet. It could mean you ran over your neighbour's lawnmower with your truck and are buying a replacement of whatever model they had. It could mean your kid wants to earn money by mowing lawns over summer and you wanted to support them by funding the mower, or that you got a job at a lawn care firm and need to buy the tools they use for yourself, it could mean you took advice on which mower to buy from a friend and don't have any personal knowledge of mowers, or that a shop had a sale, or that a shop had an attractive smooth talking lawnmower salesperson, or that you had a breakdown and need to finish mowing before the rain due at the end of the day and had no time to do any research or like/dislike anything, or that you are supporting a mow-for-charity drive for a group going to mow churchyards and you are just buying within the budget that the volunteers donated, or that you aren't technical and misunderstood that you need an Apple lawnmower for your bank app because they advertised and told you that you did because companies employ highly skilled professional manipulators working full time to frame and distort the truth and your access to information in their favour...
You might also argue that if I want a silent laptop with long battery life that is a "proper *nix" and not a limited WinRT/ChromeOS/Android then I don't have a choice and am therefore not exercising a proper informed choice so the signal from it is misleading.
