It doesn't matter to Truth Social that Trump got his account back on Twitter. That's because Trump made a deal with Truth Social where he has to make posts on Truth Social and he can't make the same post on another platform until the 6-hour time limit has passed.
With his upcoming election campaigns in 2024, anyone that wants the latest content from Trump will have to go on Truth Social. Those that don't care about getting the latest content from him and prefer to view their content on Twitter will have to wait for a while.
