What is the REAL Theme of Shavuos?

In last week's Lomdeha Friday Seminar (4/30/21) we learned three answers to the question, "What is the theme of the Chag ha'Shavuos?" - that of the Ralbag, the Abravanel, and Rav Hirsch. In every machlokess there will be strengths and weaknesses to each side, and we attempted to identify the strengths and weaknesses in each of these three. We ended off with a handful of questions that remain to be answered. My hope is that this shiur paves the way for the next level of understanding!
