Because you're going to use what these companies produce, since their products dominate the market. E.g. your smartphone is going to be either Android or iOS, no matter how I abstractly would like Sailfish / Jolla to succeed.

That is, these are not woes of globalization, but woes of monopolization of a market, partly due to the natural "winner takes all" dynamics of said market.

BTW both EC and USA have the same sort of problem with a lot of things manufactured now in China, with domestic know-how lost.
