Palestinians in Gaza are protesting against Hamas because they are tired of being pawns for the terror group's political agenda. Given the devastation Gaza has experienced, it is unsurprising that so many Gazans would rise up against the people in power.
Palestinians should continue to pressure Hamas to release the hostages and leave Gaza if they want the war to end. Hamas' terrorist activities are what led to Gaza's destruction, and if Palestinians in the strip want to live a normal life, they must reject the rule of terrorists.
Contrary to the reports in the mainstream media, the protesters in Gaza are calling for the end of Israel's genocide. Of course, Palestinian society is not a monolith, and there are surely Palestinians who disagree with Hamas' ideology. Nonetheless, it is clear that outside forces, namely Israel and the PA, are using these demonstrations to advance their own political objectives.
