Not even Israel claims it is legally part of Israel.
Not the government. Not the courts.
The Israeli government has, until the "disengagement", insisted in court regularly that Gaza was under belligerent occupation.
This was an important stance for them as claiming it as Israeli territory would give petitioners reasons to ask courts to apply Israeli civilian law. Israeli courts have accepted this stance many times over the years.
By claiming this, any annexation would be a war crime (but to be clear, Israel has never claimed to annex Gaza, on the contrary, Israel has claimed it has ended the occupation and given up control - a claim that is not uncontroversial given the level of control it still exerts)
[EDIT: And, unironically expect this deal and Karhi's statements to feature in future lawsuits as evidence that Gaza is still under belligerent occupation; this will matter greatly, especially now, as an occupying power has humanitarian legal responsibilities that can be challenged in Israeli courts if Israeli courts were to agree there is evidence Israel is still an occupying power]
So under which authority is Gaza legally part of Israel?
You mean legally part of Israel from Israel’s perspective, right? AFAIK neither the west bank nor the gaza strip are recognized as legitimate territories of Israel under international law but I admittedly know very little about international law :)
Israel explicitly rejects Gaza is part of Israel. Some Israeli politicians might claim otherwise, but the government policy has been to refuse claims it is since '67, and to now insist it's not even under occupation.

And any country where they don't have approval by the local spectrum operator.
Unsure if it's changed, but I know in South Africa Starlink connections are/were _technically_ illegal since it is an unlicensed telecoms connection. Basically unenforceable by practical means to stop consumers though, and some hardware importers advertise without issue.
The Oslo accord gives Israel right to control the airspace, but also gives the pale stone the right to operate an airport. So the accord does not give Israel sovereignty over the land.
Israel denies that they are occupying the strip, so it’s hard to say that even Israel is claiming it as legally theirs.
AFAIK the only place where Starlink is operating illegally is Iran (where presumably Elon has no business interests that can be threatened).
