Been a proton visionary subscriber for a number of years now. I am satisfied with it and do not regret leaving that part of the android ecosystem.
I did just get an email invitation for a photobackup beta program, so i am excited to see what that us about.
If you're referring to the FE and PE tests as being required. They are required to be able to get the extra cert, but not to be am engineer. Most engineers are not PEs, and you don't have to pass the FE exam to be an engineer.
