Do you agree with Sony's well-paid and successful lawyers about their interpretation of copyright law just because they're well-paid and successful, and thus must be smarter and know more than us "basement dwellers"? (I thought Trump got really mad about that term when he thought Hillary was using it disparagingly, but i guess the rules have changed now.)
I'm not going to claim I know more than the Sony lawyers or Trump, but opinions about IP law seem to differ quite a bit not based on intelligence, but on whether you've become wealthy because of big corporations (either owning them, getting paid a large salary by them, or getting lobbied by them.)
On top of that, there's at least some correlation between being old and not understanding computers and the internet.
So even if Trump is very intelligent and successful (citation needed,) as a very old and relatively rich corporate owner i would not necessarily expect him to understand why it's bad to let corporations sue people into the ground for things that ought to fall under Fair Use.
That said, even as someone who voted for Hillary, I'm glad Trump (seems to be) carrying through on his promise to block the TPP, regardless of what his reasons for doing so actually are. I don't disagree with _everything_ Trump does and says just because Trump is the one doing and saying it.
