For most of the period since 2005, it has been a joint Israeli-Egyptian blockade, not an exclusively Israeli one. That has recently changed now that Israel has militarily occupied the Gaza side of the Egypt-Gaza border
But I do find it interesting how Israel gets exclusively blamed for something which Egypt also had a hand in - and they weren’t doing it because “Israel made us”, they had their own security reasons - they feared Hamas would support Islamist rebels in Egypt.
It does seem to support the claim that Israel gets “picked on”, when a joint Israeli-Egyptian blockade gets presented as an exclusively Israeli one
