Are you privy to the private discussions between Trump and the heads of TikTok, Apple, Google, and Oracle? Or are you simply assuming there have been no such private discussions?
Not actions, but legally binding statements of intent. If Trump offered a binding statement to the heads of all major players that he intends to offer TikTok the 90-day window and work out a "deal" once in office would be more than sufficient justification for these companies to ease enforcement until things become more resolved.
There is no mechanism by which Trump can offer a statement of intent that legally binds him to following that specific course of action after he becomes president.
