I went to re-read the article and found the link no longer leads to the article.
That article focused mainly on how difficult it was to get a straight answer, and complete data from the FDA.
Couldn't find that article again; while looking for it I found a better overview (similar case, more complete sense of context and actions)

It still strikes me as an unbelievable amount of foot dragging and evasion by a public regulator.
