Summary: The above is important because of the timing. After 5+ years of pension fraud at Sirius 'Open Source' the company enrolled staff without paperwork/signatures and barely with any consent (in late 2016); to make matters worse, a few years ago it upped staff contribution levels without increasing its own, in effect forcing staff to send even more money (one's own money, not the company's) into this dubious pot with uncertain future.
There have been more efforts than we can to count or can enumerate (probably over 100 such efforts) to gag us and to prevent us writing about what has happened
