The way in which getting hacked works these days is that you as the user will never know. They will just silently exfil your data, and also use you to get to others. You will be none the wiser.
If it's so secret that nobody will ever find out, then I'm okay with it.
On the other hand, it's true that some people find out their credit score is trash right before buying a house, or that their name is involved in terrorism when applying for a visa, etc.
You should not be okay with it because they will most definitely use it to exert power over you. They are not professors or space aliens that are doing it for academic curiosity. It can be the government that wants to lock up someone, either now or in the future, or anyone that wants to steal your hard-earned crypto. It is not okay. These days they will also pass it through their AI, and potentially also use it to tune their AI.
One would never know until one loses their crypto, or one has the government hurting one's freedoms, possibly even using parallel reconstruction, or one gets blackmailed. If one doesn't know that their phone could've been hacked, one will be left wondering what happened.
