So now you're claiming that the being is only "omniscient" because it forces us to act according to its plan?
I don't accept this; I want to consider an entirely passive, powerless omniscient being.
Do you claim the omniscience itself, without any ancillary powers, eliminates free will?
I think the general claim is that the existence of an omniscient being (however passive) precludes the possibility of free will.
Actually, even the possibility of the existence of an omniscient being (however passive the being or remote the possibility) precludes the possibility of free will.
We do not control the movements of the moon; however, we can predict the movements of the moon with almost perfect precision by applying comprehensive knowledge of the forces that move it. This is strong evidence that the moon does not choose its own course, and it's also strong evidence that no sentient agency with free will chooses the moon's course, because those hypotheses do not account for such predictability.
An omniscient being whose omniscience were based on perfect knowledge of the causal forces that move us (which of course an omniscient being must have, if such forces do exist) would show we lack free will just as our knowledge of the moon's orbit shows the moon lacks free will.
What about an omniscient being whose omniscience were based on direct perception of the world from a future or timeless vantage point? In that case the moon analogy doesn't work, but
The moving finger writes, and having writ, moves on
nor all thy Piety nor Wit,
Shall lure it back to cancel half a Line,
Nor all thy Tears wash out a Word of it.
We don't, in the present, have free will to choose our past actions; and the immediate existence of any vantage point in which our present is the past likewise precludes (without even the need to posit any observer in that vantage point) any free will to choose our present actions.

So why does the Bible call God omniscient?
Exaggeration. Especially in the face of numerous passages in which God makes decisions, reacts to events with every semblance of surprise (that is, learn things), and changes His mind. An omniscient being by definition cannot learn anything, cannot make a new decision, and could only appear to change his mind if he were deliberately acting silly.
If
I were a mighty king of some appalling bronze age civilization, I'd be more insulted by an insinuation that I couldn't learn anything, than by an overt declaration that I didn't already know everything. But that's because I'm an educated member of an industrial civilization. Back in the bronze age, kings (like everyone) were primitive screwheads; they were probably too busy figuring out new ways to shove sharp objects through their own dicks to worry about perceiving the subtle insult in flattering words. So, mighty kings would kill you (probably after shoving sharp objects through your dick) if you didn't agree with them that they know everything.
So when people contemplated God, they had to imagine that God at least is as mighty as King Dickstabber VIII. Hence, God goes down in print as being omniscient.
