You are moving the goal post. But you're right: Signal's E2EE is miles better than telegram's.
I was just trying to point out my experience in getting people to switch, most of the time they have different prioirities.
Most if not all of their attacks are inexcusable. Calling a competing OS, CalyxOS, nazi sympathizers is unacceptable and when I first read that I started seeing the red flags.
Nothing is open about GrapheneOS aside from the source code. We officially know nothing about the leadership, their current plans, what their finances look like or even who this new mysterious OEM is.
This depends on if you count adware as malware, and where you draw the line of spyware.
For me personally, I think both the App Store and Play Store are mostly malware. Ironically, third party stores like f-droid have the least amount of malware.
