Some of them definitely. According to Dr HA Hellyer who was interviewed for the article:

“I keep hearing this from different people connected to the ground on Gaza that there’s a mini civil war brewing between Hamas and anti-Hamas figures,” he said.

“But the anti-Hamas figures aren’t people like the Palestinian Authority; the anti-Hamas figures are collaborationist forces with the Israelis."

“From what I’m hearing, Hamas seem to also be going after traditional families and traditional tribes that simply don’t want Hamas to be in charge, not because they’re getting support from the Israelis, but that they just don’t like Hamas.”
