There's another big factor at play: it's become increasingly easier to film yourself in combat and now encouraged by leadership for propaganda reasons.

I've been going to r/combatfootage everyday for the past ~3 years; it has exploded in popularity because like a lot of things in life, war is now recorded and disseminated wide. The ukraine war, specifically with drones outfitted with explosives, has shown this. GoPros seem almost standard for combat troops.

I have to imagine Israelis are learning about the conflict in realtime partly through the footage Hamas is releasing. The fact that footage is so unprecedented (fighters air gliding in, a Hamas reporter reporting from inside Israel) probably adds to the demand for this content.
