Those quotes do not prove your point as they do not prove what they say from the text of Scripture.
My point is simply that Jeroboam's sin is that he violated YHWH's commands regarding his worship. That what 1 Kings 12:32 is speaking about is his moving the Feast of Tabernacles. Those quotes prove that my view is not a novelty in reading it that way, indeed a Puritan and respected conservative scholars read it that way too.
That may well be the case, but this view has not been shown to be Biblical. And even on an NPW basis there is nothing to stop Jeroboam setting up a rival Feast of Tabernacles as long as he did not stop the original.
