Conceptually, the idea that an individual signals their support for a business by "voting with your dollars" makes logical sense. However it breaks down for a few reasons I detail below.

1. Illusion of product choice. Apple and Google are the only realistic options for 99% of smartphone users in America. You'll say look at all these other choices and point to a handful of alternative options, however unless you are in a completely different culture, or decide to join a counter-cultural movement you're going to choose a smart phone from Apple or Google because that's the culture we live in and you will be out of the loop if you do not. You might quibble that people could do something *if they only did [x, y, z]" but that's not how groups of people work and you know it. I think at this point over a TRILLION dollars has been spent convincing everyone that if you don’t have a smartphone (with blue text) then you’re not part of the real culture. Bernays proved long ago that propaganda works and it's literally the driving external motivation for our entire culture.

2. Illusion of organizational choice. But let’s say you did vote with your feet and you want to support Nokia. Great, however now all you're doing is supporting another major corporation that wants to be in the same position as Apple, but they just have different owners in a different country. Switching didn't do anything to actually diffuse power, its simply choosing a different privately owned dictatorship to align to. Apple and Google are really no different here, so choosing one over the other nets the same thing in terms of concentration of economic power.

3. Political power. The power that these companies wield in the regulatory capture game reaches far beyond any choice you may think you have or any chance you have as a small company to have an equivalent voice – if for no other reason than you can’t afford a congressman or supreme court justice. So all those "choices" you want still have to comply with whatever the corporate lobby thinks the law should say about technologies and they aren’t bashful with writing legislation. (Every government has their acquisitions system captured by major capitalist corporations)

4. Companies delegate responsibility for externalities. Recycling is a great example here. It's well known that the plastics industry has decided to "pass the decision" along to consumers by stamping their products with 1-5 recycling indicias. Problem is, most recycling systems cannot process or do not have recycling demand for anything 3-5, forcing consumers to do the work to differentiate. In fact, these same plastics companies KNOW that they are not recyclable yet intentionally do not reduce usage, meanwhile greenwashing their products to convince consumers that they are. Ok now do that for every other externality or illegal practice like slavery wages and wage theft, PFAS, CFC's, child labor etc... and there would be basically no companies in business

5. Consumers must know everything to make an actual informed choice. OK, so you say, “well I’m smart enough, I want to make a purchase that is good quality, has a net positive impact on resource use, uses pro-social labor practices and is inside my budget” in order to do this you need to spend an hour researching every supply chain and review etc… to get past the submarine articles, general marketing propaganda, obscene obfuscation of operating practices and on and on and as a result almost nobody has the time or energy. So then people look to third party review sites (all corporate sponsored) so you can’t actually trust the reviews.

The fact that people COULD do something differently is held back by the fact that most people WONT because corporations have structured everything to support the structure that supports them. In no way is this democratic because it doesn’t actually include what the alternatives could be and WE DO NOT BUILD INFRASTRUCTURE FOR ALTERNATIVES. So doing anything other than scamming people or trying to find a sucker left holding the bag (aka an EXIT opportunity/Liquidity event) is “off the beaten path.”
