ZStandard is garbage compared to LZMA2. Why? ZStandard has bugs and is not exactly production stable. 7Z is far more stable, and RAR is incomparable. 7Z and RAR have been around for over 20 years, extremely predictable and stable and have loads of features that ZST does not. ZST is not a general purpose long term compression format, unlike 7Z or RAR. It is only good for web servers serving webpage assets to users in-transit.
GrapheneOS
GrapheneOS is pure snake oil with a disgusting sole developer that believes in pushing corporate Big Tech propaganda, harassing and witch hunting any critics, having a little social media army with sockpuppets to do this, abuses mentally challenged by hiding behind “autism” label (Louis Rossmann has a nice video), falsely claims he was swatted without giving evidence or coverage in local Canadian media and blames everyone from redditors to community mods to YouTubers and so on. It has been 10 months at this point since the claim.
I covered this disease for about 5 years, and it emanates from the same sewer that “security” clowns like Brad Spengler and madaidan do in Linux community. All they do is either push their bullshit solutions or push corporate Big Tech propaganda and hate any FOSS project they think will not worship them.
One thing they also do is sell you the lie that it is the only thing that can give you any mobile privacy and security. Everything else is a failed joke and this thing is the only thing that works. They go to lengths of telling people to fly to other countries to get a Pixel. https://i.imgur.com/Yv9nvxy.jpg And they make fake claims about buying $1 million Israeli Cellebrite kits and them not working against GrapheneOS' "Titan" security for bootloader and other kinds of attacks. https://i.imgur.com/woNxPhx.jpg
