I can't describe how incredibly stupid this is. This is peak dystopia. An absurd example from history - "maybe we should rethink the Inquisition, no? They are kidnapping and torturing people based on no evidence" "Don't be a downer!".... "Let's brainstorm on this religion thing a bit with its pointless wars, flying airplanes into buildings and killing people?" "If you don't have anything good to say, don't."
Now - Matrix and Signal exists, but it takes two to tango. If you have no one to message there, because everybody uses iMessage/WhatsApp/Messenger, you are screwed.
Open source phones and PCs exist, but they are much more expensive for the same configuration and the open source software has its own problems. Just look at the whole Linux landscape. I just looked up System76 laptop with i7, 8 GB RAM and 240 GB SSD - it comes out at 1300 dollars. That's more than the brutto average wage in my country for the same configuration that costs about 700 dollars if you buy from mainstream brands.
I got disillusioned with open source when I tried connecting an iPhone to Linux. This is what it looks like in 2021 - https://itsfoss.com/iphone-antergos-linux/ . Full of esoteric terminal commands which operate a program written by some dude from who knows where with no guarantees what it really does, because I am not gonna bother learning about iPhone+Linux+USB delicacies enough to understand that code.
So in my opinion, it's easier to actually regulate the big corp overlords.
