To recap: Sidious pins the brothers without visible effort whilst they visibly struggle to free themselves. They are released not through any discernible efforts of their own but because Sidious willfully frees them.
Whenever he did have his face showing physical effort? When he fought Yoda, he either grinned or laughed. In final lightning contest he had the same excited grin with ohshit face at the last moment but now expression of trying to fart or something, which seems what you expect to see on his face as a proof.
This, again, assumes Sidious can't temporarily put Dooku out of the fight. Given that he TK'd the Count across the galaxy with no visible effort... I'd hardly conclude that this is out of the question.
Do you have proof that TK across screen requires more effort? Logically I would agree that it requires more effort, if not outright impossible. That's rather another Lucas' stupidity.
Again can you prove that Dooku tried to break free? If he did, that would mean defying Sidious, which as apprentice he did not dare to do.
Regardless, I want to present some new evidence:
" What happened next, Luke only felt: the invisible hand of the Force clamping down on his throat. His vision narrowed instantly. The blood to his brain had been choked off. Five seconds, he thought. Five seconds until he lost consciousness.
Maybe less.
He reached out in the Force, trying to find the Qreph who was attacking him—trying to find either Qreph—but he was too dizzy already. His hearing started to fade, his vision narrowed to nothing.
Three seconds. Maybe.
Luke launched himself into a Force leap, whirling his blade through a Jedi attack pattern, whipping his feet back and forth in blind snap kicks and targetless heel strikes. His hearing faded to silence, and he felt himself starting to drop … then the ground came up beneath his feet and his knees buckled.
Desperate to locate his attacker, Luke reached out in all directions and pulled, grabbing at every being he could sense. He felt a jolt of surprise from Leia and let her loose. He found the Qrephs just ahead,
standing well apart, two beings full of fear and anger and hatred. He pulled harder and felt them slide toward him, their fear blazing into panic and their anger deepening to rage.
The Force grasp slipped free, and the blood came roaring back into Luke’s head. His hearing returned first, and he heard Leia a few meters to his right, her lightsaber growling and hissing as she blocked a fork of Force lightning."
I've always argued that characters can be caught off guard during a fight.
This is FotJ Luke - his strongest incarnation. Yet, you can see that he can't simply break a Force choke by pushing out with the Force or some sort. And those opponent are not stronger than him. It is evident by the fact that Leia fights along him and does not get choked herself or electrocuted.
1. It proves that when Force user gets caught off-guard with Force attack, it is really hard to break from it even, if you are the most powerful Force user known.
It explains why Maul and Opress couldn't break Sidious' grip. First his attack was unexpected giving them no chance to block it. Then they hit hard against the wall and pressured so hard that durable glass nearly breaks. Simply put they were in no position to muster any possible defense in that situation and I admit that at that point he could break their spine, if he wanted or do anything he likes. But arrogance led him to gamble with his life.
2. It proves that the only way to break Force choke is by directly attacking with Force in return. As example that's how Galen Marek broke Vader's grip.
Dooku would not dare to attack Sidious with Force, he was trying to convince instead. I might as well mention Caedus, when he got caught off guard. He was in exactly same situation as Dooku, he could break out but that would mean Force attacking Luke. We even have TCW cutout scene due to time limit, where Maul pins Sidious against the wall. And guess what, Sidious was unable to break free directly, he threw a lamp at Maul instead. But of course you will conveniently ignore it, despite the fact that authors considered something like that as a possibility.
There is a reason why Force users mostly engage with lightsaber duels. That's not because they are retarded to choose not to overpower with Force, when they can. Yoda is not retarded, when he decided to engage Dooku in a duel twice, he simply would not be able to subdue Dooku with Force. That's because they need to catch opponent off-guard, otherwise it will be blocked. Like in example, where Kenobi blocked Anakin's attack. Or where Anakin and Kenobi blocked Dooku's Force wave.
That's why Sidious Force blasted Maul and Opress only at beginning, when they least expected. And another Force blast, when Maul sprang for attack with lightsaber high up. It's all about using Force attacks at the right moment.
