I think this person very well knows what they are talking about

TikTok got forced to host all on Oracle servers and store all information there. And have mandatory code inspections.

This was after Trump tried to ban it citing “security concerns”.

The funniest part is that back then Microsoft was supposedly trying to buy TikTok and Trump made sure that wouldn’t happen

Microsoft was reported to be in talks of acquiring TikTok. Later that day, President Trump announced plans to ban TikTok in the United States, and signaled opposition to any sale to a U.S.-based company. Trump’s ban threat and his indication he would oppose any sale to an American buyer was condemned by TikTok users, many of whom argued that national security concerns were being used as a cover by the administration to justify a ban as retaliation for pranks aimed at Trump by TikTok users (particularly, a ticket-purchasing effort to inflate projected and depress actual attendance of his June 20 campaign rally in Tulsa, Oklahoma) and other content satirizing Trump or critical of him and his actions, especially in relation to his response to the George Floyd protests.
