I'd say you're paranoid. Nobody cares about you, and they won't invest billions just so they can see your hot nude pictures. There are much easier ways to get information out of a phone, no need for a backdoor.
If there were ever any backdoor in some phone, it would have been found. No smartphone company is gonna take that chance that someone will find their backdoor, it will literally kill the company.
Whether parent is paranoid or not, Pegasus literally is used to spy, just because the state might not care about his hot nude pictures does not mean they don't care about other phone usage.
"While NSO Group markets Pegasus as a product for fighting crime and terrorism, governments around the world have routinely used the spyware to surveil journalists, lawyers, political dissidents, and human rights activists."[0]
Information these they can be much as powerful as a bomb, for example, I could learn more about your calls and discover that you do something immoral but not illegal and use it to blackmail you.
I'm guessing you missed out on the Snowden revelations? Or the news articles about federal agents literally laughing at private dick pics.
And your second paragraph seems to go on the premise that the average person care if there is a backdoor.
I don't know why you wouldn't take security seriously, when even the US government is telling everyone to be careful where they supply their devices because of spying. Just don't trust them to point the finger the right way.
The UK government is known to spy on anti genocide protestors.
The US government is known to spy on anti ICE protestors.
If you have an opinion your government doesn't like, or a potential future government doesn't like, there's a good chance you have or will be spied on.
Perhaps you lack a single opinion worth caring about, but most people do not.
And I'd say you don't understand how state-sponsored tracking and spying operates
> Nobody cares about you
This is such a low-iq argument I cannot even. Yes, nobody cares about OP, you, me, whatever - until they do. Not to mention general harvesting for profiling and propaganda reasons.
General: What do people in this city/country/region/etc are thinking - This is the main one where the data is used and collected, then grouped. It is extremely powerful information for targeted agenda whichever it might be.
Targeted: Oh, you or someone from your close ones went to a political protest? Too bad we have all this information to put you and your family in jail - This is where suddenly they will care about you, even when it is NOT YOU but someone from your close circles were the ones upsetting them.
Sometimes you become a target purely by chance. You may witness something you should not have seen, are at the wrong place at the wrong time, the "algorithm" glitches and increases your "thread level" by 5000%. In most of these situations preparations like running graphene os can be quite the boon.
Or think of friends and family. When they become the target, you are prepared, you have the knowledge and tools ready, you can be the guide that helps them navigate a hostile digital world.
