Is it a joke? Guys who joined as DECs where proposed the job and they would have been quite stupid to turn it down. This simply happened because in house FOs were not bidding for the job, that's all. The old aviation saying "never turn down any upgrade" seems to be true.
On the other hand those DECs are a very good financial move for Tfly as they are the cheapest Capts they have ever had with a seniority close to zero.
Concerning MFF and DECs, I really don't see that happening in the near future. Guys flying MFF will be selected according to the seniority list, so DECs should be among the last ones to do it.
Anyway all that is just rumours, wait and see and in the meantime enjoy getting paid for so little flying!
