I don't like Android, I don't like iOS. What do I buy ? Not the one that is best for me, because I don't have a real choice, but the one I will hate the least.
Not buying is also a possible decision. You should of course choose this choice if all other available option have a negative net value for you. The fact that you decided for Android or iOS shows that both of these choices have a positive net value for you - so what are you complaining about?

Android suits me more, but I would like to be able to run multiple VPNs at the same time. What do I buy ?
I didn't buy Android because this is what I want, but because it's the closest. But how do I drive the decisions to where I want ? Am I supposed to wait that a million alternatives are created and have the same level as Android, then only can I buy what I need ? This just doesn't work.
This means the vendor makes no money from you. If a lot of people decide this way, the vendor will have to adjust or go bust - this is called "market adjustment".
The fact that you did buy tells the market that what you bought is of net-positive value for you.
This doesn't mean the market is efficient. It means the market misunderstands itself.
