Problem is that Isa 44 is DtrIsa and not TritoIsa. Your cite refers to TritoIsa.

Quote:
Two crises occurred between Proto-Isaiah and Deutero-Isaiah. The first was the late 7th century Deuteronomistic reform of official Judean religion under king Josiah, who banned many elements of the old polytheistic cult from the Temple, and the sudden collapse of Assyria and the rise of Babylon to take its place; the second was exile of the royal court, the priests and other members of the ruling elite following the Babylonian destruction of Jerusalem c.586 BCE. Deutero-Isaiah delivered his prophesies to this group, which was actually quite small – the majority of the population stayed in Judah.
By the middle of the 6th century the king of Babylon was Nabonidus. He alienated the powerful priests of Marduk, the official god of Babylon, by taking up the worship of Sin, the god of Harran (a city in northern Mesopotamia), absenting himself for long periods from the city and neglecting crucial ceremonies. He also neglected the rise of powerful new enemies, first the Medes, then the Persians under Cyrus the Great. In 550 BCE Cyrus defeated the Medes, and had allied himself with the priests of Marduk, and the fall of Babylon to the Persians became a real possibility. These events date Deutero-Isaiah's earlier prophecies. Chapters 49–55 probably come from a slightly later period, after Babylon had fallen to Cyrus and the return to Jerusalem became a real possibility.
Dating DtrIsa roughly around 550-530 makes a lot of sense, but claiming you know that
this particular passage was written 20 years earlier than
that passage would need a lot of further detail. Usually, prophecys, if they are used to date passages, are taken as
termini post quem, not
ad quem (such as the destruction of the temple in Mark as t.p.q. for Mark at 70post at the earliest, for example).
In all of the latter prophets, there's a lot of later additions, redactions and the like. It's pretty much up in the air currently if "Deutero-Isaiah" is even an individual or not rather a group of people (priests, for example). The "existence" of TritoIsa is debated as well.
