It may be a private phone, but you don’t really know whats going on under those proprietary blobs. Yes thats not good, but also a problem of many common Linux distributions. If you have any linux-firmware-* packages installed on your system, they also contain similar binary blobs for the firmware. E.g. Intel or Qualcom wireless cards. But you can utilize all tools up to strace under Sailfish OS, to see what those drivers are accessing and check that they don’t do anything bad. Under Graphene OS, you can not do this. (But its resonable to trust the very privacy focused developer that they have checked and tested this and isolated them as far as possible on the OS level)

Sailfish OS is the definition of proprietary software. You need to buy a subscription if you even want to install it on third party devices. Again this is not correct. If what you claim is true, how comes that the OS is available on all these devices?. Sailfish OS is open Source at its core and easily ported to new devices. What you can do is pay for the licensed content on official devices. That enables automatic updates and proprietary software as the MS Exchange support and the Android App Support. Though for the later you can also install Waydroid because, you know, its Linux! Paying Jolla however gives access to a more comfortable solution and support development of the platform.

It’s like Windows Um… no. Can you port Windows to a new device? No, its source is closed. Does Microsoft support people hacking their OS? No, Jolla has community meetings for that. Do you have full Access udner Windows? No. Does Sailfish send your data to a third party? No. Does Sailfish show you adds? No, Does it force you to use AI? No and so on and so forth.

Please don’t hate on the one European company trying to do things right. Support them in making things better.
