It seems like striking fear into the hearts of users to make them realize a ban is really on the table is in their best interest. They want to not be banned, and giving everyone a 48 hour show of users on the platform counting down to the end, then being really upset when they think it's gone is a great demonstration that people want their Tiktok.
* Trump gets a free layup to look like the hero for unbanning it
* Trump will think hard and heavy in the future about banning it again, knowing there's a lot of passionate young people that will reconsider voting for him next election if he does
Plus has there ever been a US president that came back after a term away? Usually when a "new" president comes in you figure they'll be running again next time.
Grover Cleveland also had two non-consecutive terms, and the twenty second amendment is pretty clear in it's language that you can only be elected to the office of President twice.

Seems like a smart move to me.
