I lean towards suspecting this report is accurate or at least has some truth in it, but I don't see it as siding with Iran.Also, this report, if true, is infuriating to me as an Israeli:

Again, if true, that means that the US favored an enemy and a threat over a long-time ally, and was willing to spend (essentially waste) millions if not billions of dollars to shoot down the drones and rockets. Israel and other countries who also shot down the armaments also wasted a lot of money.
The United States warning that they will take action if the assault goes beyond certain limits is not the same as giving a blessing to attacks within those limits. They are restraining the Iranian assault, not endorsing it.
The way things played out gives leaders in the United States and Iran a diplomatic 'out'.
The United States gets to avoid military action that would expand the scope of the current war while demonstrating it's commitment to defending Israel in repelling the attack.
The Iranian regime gets to beat their chest and pacify their military and supporter's bloodthirst after the killing of the Iranian government and diplomats. They can also frame themselves as friends of the Palestinians without actually having to get more involved, which helps them with their domestic problems with fanatics.
Israeli leaders are now in a position where they get to gauge how they will navigate the situation.
They can follow the advice of the international community and avoid direct retaliation, framing this as a victory over Iran and as a triumph of the dome as the Americans have. Or they can retaliate and risk escalating it into a war with a military response.
It seems to me the price for peace in the future is much lower if they follow the American's lead.
