Because Big Tech demands big profits. They can not exist in worlds where they can not have a monopoly or oligopoly. Smaller companies and ISVs, on the other hand, will be better off if their market is commoditized. They won't have to spend so much to compete in R&D, they just need to find each the best way to serve their (comparatively) small customer base.
