I recently saw this video from a YouTuber (Switched to Linux) that shows that PureOS doesn't have any of the special modifications that the website says it does. I decided to test this in my own VM, and so I downloaded and verified my ISO for PureOS. In the live environment, I get the same results that Switched to Linux (the youtuber) mentions, with none of the extensions installed, Google as default, etc. After the installation, the same results show up.
For "A user friendly, secure and freedom respecting OS for your daily usage", this doesn't seem really secure at all. This is basically a version of debian with a "secure" browser, and gnome slapped on top of it all (with a Plasma version on the download server). This makes me question about the Librem 5. Will it have the same problems as this OS does?
