Y'shayahu / Isaiah 5:1-6 is speaking about a time 700 years before Jesus, when G-d is judging the Jewish people. It has nothing to do with Jesus and never mentions a "son of G-d." Note that the list maker does not tie this claim to a verse in the Christian bible. . .
Yet again the list maker has lifted a passage out of context and ignored the very words of the bible which state that the vineyard belongs to G-d (not the "son of G-d" and that the plants in the vineyard of the Jewish people!
The analogy of Y'shayahu / Isaiah 5:1-6 is that of a man planting a vineyard expecting grapes with which to make wine. The grower tends his vineyard lovingly, doing all he can to ensure a good crop, but instead it sprouts forth בְּאֻשִׁים -- wild berries that are inferior. In frustration and irritation the man removes the fences and hedges he had protecting the vineyard, allowing it to be destroyed -- overgrown and filled with thorns. Y'shayahu / Isaiah says this is how G-d has treated the Jewish people -- with tenderness and kindness, tending to us hoping we would grow into just and good people, but instead the majority of Jews in Judah (the southern Kingdom) were going through the motions of Jewish observance, but they were not being good to their fellow Jews. The core of being a good Jew (a good person) is to be good to your fellow humans, charitable and kind. Yet the Jews of that time were not taking care of their own needy people.
Isaiah tries to warn the people to change their ways or else suffer the consequences. The people ignore Isaiah's warnings because they think they know what G-d wants -- to have the mitzvot followed -- but not realizing that motions are not what G-d wants, He wants justice and righteousness. By the time we reach Y'shayahu / Isaiah 5:13 where G-d decrees "Therefore, My people shall go into exile because of lack of knowledge, "
The exile is both punishment and, as a parent punishes a child, done in the hopes that the child will learn from the punishment and become a better person. Keep in mind that when a future vision is given, and that vision is negative (exile) it can be avoided by doing the right things. Isaiah is warning the Jewish people to avoid the punishment, stop "going through the motions" of bringing sacrifices without meaning, and ignoring the important things such as charitable acts and good deeds.
The Book of Y'shayahu / Isaiah revisits the historical period covered in the Book of M'lachim / Kings (authored later by Y'rmiyahu / Jeremiah circa the year 3352 (410 BCE). The focus of Sefer Y'shayahu / Isaiah is not on the history of the time, but on the warnings by the prophet to the Jewish nation to return to observance of G-d's instruction book -- the Torah. Isaiah lived at the same time as Chizkiyahu (Hezekiah), a descendant of Solomon (and it was he who recorded Isaiah's prophecies). At the time of Isaiah the prophets Micah and Isaiah are preaching in Judah (the southern kingdom) while the prophets Hosea and Amos were preaching in the northern kingdom of Israel.
In the time of Isaiah people were not being charitable -- they were not taking care of their own breathren -- and this is the main theme of the entire book of this prophet. The Orthodox Union has an interesting short article about chapter 5, along with a video. Link.
