Looks as though X made the transition from Trump to Biden without breaking links

I was concerned that links from this blog to X posts by President Biden and trailblazing VP Kamala Harris would be broken by the transition to dictatorship. Yet it seems that my fears were unfounded. In Why do the non-Deplorables deplore the Trump shooting? I included a tweet from @POTUS and it now magically appears as content from @POTUS46Archive:

Fair to say that X is the only major Silicon Valley company that cares about preserving older pages/links?
