They have been very good at making a profit - it is true.
Well, FDEV product portfolio and financial health seems quite solid even after the disappointing EDO sales and initial figures for the latest JWE
They reported an operational loss of 1.8 millions GBP for the first 6 months of FY 2022
However, i dont think this means Doom for FDev... at most, it may mean Doom for the main culprit for this loss... Elite Dangerous
