This is not true entirely; the capabilities of DEV QA ships and the like absolutely don’t represent the capabilities of an in-universe faction.
What’s more, the Jove Directorate’s ships (Wraith, Phantom, Eidolon, etc) also aren’t intended IN-UNIVERSE to be some omnipotent vessels - though that certainly was the original line of thinking when the game first went online, with Devs as Jove (which they explicitly aren’t anymore)
Polaris as a faction isn’t an entity within the canon of EVE, just as the CCP corp isn’t - the invulnerable/omnipotent capabilities of those ships are equally not an in-universe fact, though the ships themselves can be assigned loose canonicity through their usage by ISD.
CONCORD’s power over capsuleers also doesn’t come from some outrageous power, either; they lost to the minmatar invasion in Empyrean age. The better explanation is that CONCORD has backdoor/root access to some pod systems - and as EVERY playing capsuleer originates from official schools within the empires that go through CONCORD, they’d naturally have that sort of knowledge for any player, but not any NPC who had external/more nefarious immortal origins.
in short:
CONCORD and the Jove wield enormous strength not through power, but through tech capabilities and other means; CONCORD has a degree of control over capsule functions, and the Jove Directorate excelled in espionage and info-gathering that always gave them a strong edge, alongside their still highly advanced (but certainly not surpassing the Drifters in strength) ships.
If you look back to Vak’Atioth, the Jove Directorate was in an interesting position; while their advanced, capsule-using ships indeed vastly outstripped the baseliner-crewed Amarr, they ALSO had prior knowledge of the entire operation’s plans and details, given to them by an Amarr whose loyalties and faith shifted.
