Not sure about that. As far as I can see, God is not necessarily limited by humans having absolute free will any more than it is limited by, say, being omniscient.
i'll respond to the bolded part below.
Hypothetically, humans may possess absolute free will while God remains unlimited, as God may simply give them free will, and abstain from interfering with it, despite the fact that he can control it completely if he chooses.
It's like when a King gives a piece of his kingdom to someone,
it no longer becomes under his domain, regardless of the fact that he willed this to be, in the first place.
Regardless of whether the theistic god is logically coherent in other areas, with regards to absolute or 'libertarian' free will in humans, there's no logical incompatibility. Unless you're saying that God must have absolute control over man's will too, i.e., that God must dictate man's will and choices and configure them according to His will, rather than leaving people to follow their own.
I didn't say God is the first
and only cause, I only said he's the first cause period.
What does this mean? If God is timeless and changeless and has certain intrinsic and immutable characteristics that shape his actions and thoughts, then how can he have absolute free will? How can his decisions be absolutely free if they are ultimately caused by his attributes that he possesses whether he likes it or not? As far as I can see, the theistic God must necessarily not possess absolute free will.
Well some argue (for example the Mutazilites) that God's attributes
are one with His essence.
