Sandboxed Google Play provides better security, privacy and usability. Why that is, as well as your question about Calyx vs Graphene, is answered in this Privacy Guides Blogpost.

Please don't trust what they wrote and think for yourself. They clearly have no idea what they are talking about, as I explained in another comment.

conveniently ignoring that google runs a dedicated, ccp-friendly version of google

If you had paid any attention, you'd know that the point was that on Android it's way easier to simply not use the Play Store (without compromising your security even), so Google doesn't have nearly as much control.

conveniently ignoring that there are altstores for jailbroken iphones

It is much less accessible, less supported and can be a security risk. If it was so easy, why didn't the people in HK simply do that?

conveniently ignoring the gigabytes of undeletable bloatware

Still better than iOS, which is the point of the video.

conveniently ignoring that there are several apps like protonvpn that prevents tracking in general

Using ProtonVPN doesn't "prevent tracking in general" and that you think it does is showing about how qualified you are on this topic.

shilling graphene without mentioning that one has to buy an iphone price tagged pixel to install it, not going down that installing a rom is way out of the skillset of karen mcnormie

You can get a Pixel for less, but do you know what also is iPhone price tagged? iPhones.

There's a web installation for GrapheneOS not shown in the video that is so easy my grandma might be able to do it given some time.

a rom maintained by a single guy in india who claims it's very privacy respecting

This is so far from the truth that you might as well say it's currently maintained by an alien on mars.

TLDR - for the sake of yourself and everyone that might be misled by your misinformed comments, please educate yourself. Everyone has to start somewhere, and admitting you don't know what you're talking about is much more respectable than typing bs because you don't know any better. You can start your journey by actually watching the video while paying attention, or alternatively reading about GrapheneOS on their official website.

It's not the fault of GrapheneOS that there are so few phones with the necessary security. They can't reprogram your hardware.

More importantly, it doesn't change anything about Android > iOS.

Michael Bazzell from Intel Techniques and the Privacy, Security and OSINT Show recommends it over iOS as well. I have never heared a credible argument for iOS over GrapheneOS. Personally, I wouldn't even know where to begin if I had to make one without just completely lying about everything.

Almost all banking apps work on GrapheneOS.

Stock Android still offers way more potential for privacy than iOS does.

Somehow, a few people here actually DON'T BELIEVE WHAT HAPPENS NEXT – 17 minutes of comprehensive analysis and well supported arguments in favor of the claim in the title.

Exactly:)

Wearing special anti-surveillance clothing because you want to make sure cameras can't identify you is the real life equivalent to installing ten privacy browser extensions because you want to make sure websites can't track you.
