Haven't found anything more recent in English media, but there are some German articles about the current Gaza protests against Hamas and pro peace. Translation of yesterday's Tagesschau article (DeepL, no further translation check):
Protest in the Gaza Stand up against Hamas
Shouts of “Hamas out” on the streets of the Gaza Strip: These scenes are rare. This is because the terrorist organization is cracking down on its opponents. However, many people are not deterred by this and are sending out a “cry for help”. Once again, numerous Palestinians in the Gaza Strip have protested against the Islamist Hamas and the ongoing war against Israel. Eyewitnesses spoke of one of the largest protests in years in the coastal strip. People of all ages joined the rally in the town of Beit Lahia in the north of the coastal region. It was at least the third demonstration for an end to the war in the Gaza Strip this month.
"This is not just a protest, this is a cry for help from thousands of people. We are tired of Hamas speaking on our behalf while we bury our children. We want peace. We want a life," said one participant. According to the AFP news agency, there were chants against Hamas. Some of the people raised white flags and demanded an end to the war that has been raging in the Gaza Strip for more than a year and a half. Some participants in the protest called for Palestinian national unity and a new Palestinian leadership. According to eyewitnesses, the demonstrators also demanded the release of the Israeli hostages.
Residents reported seeing Hamas-affiliated forces in civilian clothes, but they had not intervened for the time being. “They can't arrest everyone,” said a young man who joined the protests with friends. People were no longer afraid. Due to Hamas' crackdown on dissent, it is unclear how much dissatisfaction there is with the rulers in the Palestinian territory.
Israel resumed its massive airstrikes on Hamas targets in the Gaza Strip on March 18 after a ceasefire lasting almost two months. The Israeli army also launched a new ground offensive. The declared aim of the Israeli government is to increase the pressure on Hamas to release the Israeli hostages still held by Hamas. 58 hostages are still being held by the Islamists, 34 of whom are already dead according to the Israeli army.
I'm sorry but that instagram post doesn't clash with the article of one of the largest and most reputable German media houses.
