Sure, but we should also note that Palpatine never outright says he knows how to do what Plagueis did. Even when the mask initially drops, the verbiage is about “having a complete view of the Force” and “using his knowledge,” which is consistent to how he continues to discuss the topic post-Mace Murder, where he emphasizes discovery. It’s an academic seduction almost; forbidden research that Anakin won’t get from Jedi teachings.

The Force is still a great mystery, but maybe a practitioner as “powerful” as Anakin could unlock it if only he had access to all of that knowledge~. That is the function of his being gassed up, playing off of the allure of knowing more about the Force than the Jedi would tell you. It’s not meant to be a direct transaction, tit for tat heel turn.

I think Anakin still has more agency in that than just being duped.
