Why are people turning from the Pre-Tribulation Rapture position?

My self and other Pre-Tribulation Content Creators getting comments from People Claiming to switch from a Pre-Tribulation rapture position to a Pre-Wrath, Post-Tribulation, or even an Amillennial position. In this video I explore 2 theories.
1. Disillusionment from being disappointed by date-setters
2. They falsely believed that the rapture would happen before things got this bad so they assume the pre-trib position must be wrong.
