I fail to see why it is desirable to have any big tech company to begin with. Not if they possess enough power to influence legislation and crush any potential upcoming competition.

Success of tech in the US has little to do with American genius and everything to do with government welfare… which is bad though so we pretend we’re all genius hackers instead
