I think one big issue is the federal trade commission has been too shy about fighting trusts or anti-competitive behavior because they believe(d) tech is different.

They allowed FB and Google to gobble up competitors unimpeded.

Amazon is another. Their integration and breadth are a threat to businesses and consumers alike but we’re too busy enjoying next day deliveries to care.

You ask for competition but these behemoths either buy them out or smother them via anti competitive behavior; at that point breaking them up is very palatable.
