Agreed, but in the very recent past, companies were held to task by their customer base and their neighbors. That is not the case for Google, Facebook, Twitter, etc. They do not share a common....well, anything aside from the quest for profits and market share/dominance.
Standard Oil, ATT & T, banks, phone cos, and others were boken up. Shareholders often did better.
Facebook, Google have the knowledge, the means and inclination, to heavily influence elections, and your children's minds.
If conservatives can be routinely silenced, they will have to chance to compete.
Only because of "regulation" (and some government involvement) do non-economical customers (rural) get phone and utility services, mail.
Extend that to clean water, air etc.
Those facts argue it is naive to presume an entirely free market will serve users.
Every time I see the term "stakeholders," I cringe. But I realize it arose to consider the aspects of life, not adequately covered by unregulated markets.
Further some at the top of Big Tech aren't even trustworthy, insofar as we saw Google surrender to China, for market access. IOW do you trust them, too?
Finally the sttory is not done, on the degree to which our 2016 AND 2018 elections were influenced by big media.
