There is literally no way this can ever result in any impact on the market. Literally no one will ever be able to tell how many sales are made or lost because of whether or not there is a headphone jack. Therefore it is also impossible for it to influence anybody's future decision.

This is also my problem with people saying you can vote with your wallet about laptops. No company will ever be able to figure out which features someone bought the laptop for, or which choices caused others to pass it up. Therefore it is impossible for your (or anybody's) wallet to show companies what you want.

This also means it is impossible to vote about software. Or really anything that has multiple features. You can't vote about cars this way. You can't vote about houses this way. You can't vote about fast food this way. You can't vote about online shopping this way. You either buy all of something or you buy none of it. You can't buy into the parts you want while leaving out the parts you don't want. You incentivize the full package, or you don't, and lost sales are invisible and inscrutable.
