[NNagain] The non-death of DSL

[rjmcmahon]

Tragedy of the commons occurs because the demand & free price for the 
common resources outstrips supply. Free cow grazing in Boston Commons 
only worked for 70 cows and then collapsed. Over fishing in multiple 
places today are killing off a "wild" food supply.

The regulator tries to manage the demand while keeping prices 
artificially low, typically for political/populism reasons, vs finding 
ways to increase or substitute supply and create incentives for 
investment. In the U.S., they seem to ultimately give up (regulatory 
capture is a form of resignation) and let so-called privatization occur 
(barbed wire ranches throughout Texas vs free roaming) which also allows 
ownership & market forces to come into play, even if imperfectly.

I do like the idea of a benevolent and all wise regulator that can move 
society forward. I just don't see it in the U.S. We seem to struggle 
with a functional Congress that can govern and and ethically based 
SCOTUS which are not nearly as nuanced as technology and the ongoing 
digital transformation.

Today, the FCC can only regulate decaying affiliate broadcast news and 
stays silent about "news" distortions despite an insurrection that still 
threatens the Republic. Sorry to lose confidence in them but we need to 
see the world as it is.

News Distortion.  The Commission often receives complaints concerning 
broadcast journalism, such as allegations that stations have aired 
inaccurate or one-sided news reports or comments, covered stories 
inadequately, or overly dramatized the events that they cover.  For the 
reasons noted previously, the Commission generally will not intervene in 
these cases because it would be inconsistent with the First Amendment to 
replace the journalistic judgment of licensees with our own.  However, 
as public trustees, broadcast licensees may not intentionally distort 
the news.  The FCC has stated that “rigging or slanting the news is a 
most heinous act against the public interest.”  The Commission will 
investigate a station for news distortion if it receives documented 
evidence of rigging or slanting, such as testimony or other 
documentation, from individuals with direct personal knowledge that a 
licensee or its management engaged in the intentional falsification of 
the news.  Of particular concern would be evidence of the direction to 
employees from station management to falsify the news.  However, absent 
such a compelling showing, the Commission will not intervene.
