KSFO have built parallel runways that are too close together, (probably owing to lack of space), to allow ILS approaches when both runways are in use simultaneously.
KSFO have decided to reduce safety margins in order to get more traffic on the ground during busy periods.
LH's safety department - or their insurers - have undertaken a risk-assessment and decreed that night visual-separation approaches at KSFO are not quite safe enough, so have banned them.
This LH crew were - or sounded - cocky and unprofessional, and used a swear word, which (understandably) got ATC's backs' up.
ATC allowed their (understandable) annoyance with LH to influence their handling of the situation.
ATC did not issue an EAT.
USA ATC is apparently a difficult place to work right now, owing to controller shortages ? Don't know, but US controllers at large busy airports often sound stressed-out to me.
Not having a go at any one party here; just as I see it.
