This is the idea of the "clean network" originally brought forward by Trump.
Basically all tech is clean and ok if comes from the good guys (the US and allies) and unclean if it comes from the bad guys (China, Russia ...).
IMHO a sad state of affairs. We would be at a healthier and less hypocritical place if our tech was secure by design, and suppliers and platforms were subject to open objective criteria and rule of law wrt. censorship and surveillance.
I don't see how "secure by design" tech would solve the TikTok problem. TikTok isn't hacking people's devices, it's tracking them and giving them disinformation and propaganda. Secure code isn't going to fix those problems; the only way to fix them is to simply not exchange data with tiktok.com.
Well a lot of agencies do that out of the box because secure by design is not believed. Trust but verify. You see that when intelligence agents talk about cooperation between partners. So in the grand scheme of things it wouldn't really change things.
The one thing it would change though is that it would make the life a bit harder for cyber criminals(think downgrading tls connections).
And the criteria you talked about, they are open. Called capitalism, and regulations those companies operate under. Along the way that abomination of surveillance capitalism was born though.
