I am using openSUSE Leap 42.3. I still haven't tried PureOS or PureBrowser but I thought I would share these with you as you might want to check more in-depth the validity of my concern and hopefully prevent code disrespecting privacy to propagate in your systems.
FWIW here is also a discussion I started in the openSUSE forums about all this (others seem to confirm what I notice through testing via wireshark):
