Sometimes I marvel at what would be possible if just a sliver of open source talent was put to work building independent quality software for their own or an investor's profit. Marketing a product forces you to figure out what it is people actually need and deliver the knowledge and education people need to use a product well. In fact a lot of what is wrong with software from big tech companies is that individual programs are not written to make the program itself great, and the incentives generally do not encourage spending a lot of time making some part of Chrome or Safari more efficient.
Open source will never spend time marketing anything, never spend time educating an actual mass of general users as to its virtues or how to use it well, and suffer as a result. You don't have Desktop Linux that blows everything else out of the water because that would require investors to stake a lot of money doing these things, which they will only do if there is profit. PopOS gets as close as you might with something like that, but is ultimately shackled by the fact they cannot sell their software. (Enterprise is different, where I guess you can nerf the product to make money on servicing instead).
Even someone with infinite resources cannot do what a company selling something for a profit can because they are either ultimately captured by and beholden to some other interest other than the product itself, or constitutionally lack the energy to be daring and actually compete. Imagine what someone could do with a Firefox sold for a profit because of its superior functionality and superior efficiency.
