Afaik the presidential powers to enact tariffs is limited. Congress is in charge of the budget and are the only ones allowed to set permanent tariffs. He is only getting away with what he is doing because he keeps making up phony emergency reasons why we need them, i.e. the bogus Canadian fentanyl story. The idiots in Congress have already given up so many of their duties to the executive branch it's doubtful they can recapture them. Until members of Congress decide to call him out on his bullshit he will keep getting away with it despite what any of them say publicly.... And we all know that his boot lickers will never do that.
I don't have an iPhone but my daughter does.
For music I don't sync anything to her phone. I run a navidrome server and set up an account so she can stream whatever she wants whenever. I think she uses isub as her streaming app. It does allow you to download and cache files from the server to play if you are offline
As for sms, I don't know of any way to sync in Linux, but if you use Windows, the phone link app works, as several of my coworkers have set it up. I know it installs some piece of software on the iPhone you want to sync to, maybe you could do that and try running the phone link program with wine?
I also know kde connect has a link for iOS. It's not perfect but it will do the sms linking thing.
