There is no meaningful opposition to Hamas in Gaza. The Muslim Brotherhood terror group retains the support of a majority of Arab Muslims occupying Gaza. While they’re far from enthusiastic about it, the only other game in town is the PLO’s Palestinian Authority which tends to be far more hated.

Plus Hamas has a way of shutting down protests very fast and in the most direct way possible.

The Arabs in Gaza live in a tribal society of clans. Everything is determined by connections to large families. Those families have a lot at stake and scramble for a place in the power blocs that run everything. Which means they don’t just have protests.
