In reality, only some few of the best/highest-pressure companies can maintain that for any length of time. The rest probably won't profit from the distrust and ill-will caused by the rhetorical slight of hand that defines "adequate" as "well below the actual standards we consider adequate".
"Adequate" is inadequate by Netflix's standards, so it's not "adequate" it's "below expectations". Daft.
