Perhaps you missed the difference in scale between all of the last 5-7 
years versus pretty much all of that 20 years?

In other words, just to keep this simple:  They not in the least 
comparable.  Also, cf, my previous reference to incentives.

Mechanical application of a high-level script, without attending to the 
details that make the script actually work in a specific case, tends to 
lead to counter-productive decisions.  cf my earlier reference to 
barriers to entry and lack of damaging effect.

And flamboyant, aggressively hostile language like 'thumbing their nose' 
is not merely wrong, it is another attempt at gaslighting.  cf my 
earlier reference to hostile work environment.

sigh.
