RE:ViziyaSale of Viziya was done May 2020. Hard to fault Quarterhill for not realizing at the time that Russia would invade Ukraine in February 2022. Or that government stimulus would prove as inflationary as it did.
Prometheus may also have had access to synergies and/or sales leads that Quarterhill couldn't have had.
To whatever degree your story is correct, I'm happy for Prometheus. They made a bet and it seems to have worked out.
