One could argue that it’s all the centralization and monopolistic behavior which hinders tech development in the usa. So a breakup might have short term stutters but long term gains.
The creator of a specific technology getting acquihired doesn't stop others from competing with the original. If anything, acquihire is a validating signal and probably leads to more entries into the market.
The reduction of competitors and no win for the investors is somehow a signal that entry to the market against an even stronger than before incumbent would be a good bet?
