That means that country that will do that will not have competitive big tech companies and other countries will have.
Also, big companies are needed because there are technologies that cannot be produced by small companies. I do not understand recent tendency
to make them look bad. Big companies are good for country and economy. Punishing companies for success is harmful for the progress.
I think letting market decide is better choice. Overregulation leads to decrease in competition and production.
Also, what is bad in it of big companies need to compete for talents? This competition leads for better opportunities and bigger salaries. I think it is good that person has a freedom of choice were to go.
