Some of it are fake: https://www.independent.co.uk/news/world/americas/dead-sea-scrolls-face-museum-of-the-bible-washington-artefacts-a8596636.html

Others falsely interpreted in a way to back the Jewish story AND most interestingly if you didn't know this. A lot of it actually changes the so called Jewish history and shows there are multiple texts that changed during time.

The Dead Sea scrolls forgery is actually a good example of how Jews operate. They hide some parts which are inconvenient, reinterpret others to fit their narrative and add some parts to fill their stories.

For example the book of Esther was never part of the dead sea scrolls so they just tried to add small patch here and there.

Anyhow, all dead sea scrolls content must be taken with great caution since Jewish militias stole the land they were found in after 1967 and could start making their own "discoveries" ehm "additions". Worthy to note that the Jordanian government also works for the Jews and the findings made during their rule also cannot be completely trusted.
