OK, so to take the first few of those links: the first attributes this partly to ""high levels of immunity [in England]", which of course is largely due to the vaccine rollout and especially the booster campaign.
The second makes exactly the same qualification, referring to "sky-high immunity rates".
The third is less equivocal (and less grammatical): "Vaccines, alongside the high infectiousness of Omicron means COVID is now less deadly than flu, according to a number of reports."
All of which was essentially my point, ie Omicron is not necessarily inherently less lethal than flu. The vaccine rollout has shielded us from its worst excesses.
Not sure that your later point is relevant - whether the individual currently has COVID-19 or has merely had it, the effect with respect to immunity is ultimately the same.
