It's very unusual to see such criticism of these A/C on official governement controlled media.
WZ.
The largest operator of TU204 planes is effectively grounded as of Feb 3, and UN are the only with any size orders together with VIM and Rossiya.
WZ constantly complained about the planes in service, and it seems made a serious commercial error using them at all.
That, more or less means the end of the TU project commercially, which was supposed to compete head on with IADS.
Syrianair & Iranair are effectively dead as buyers.
SSJ, we have conflicting info today:-
ranging from issues of compensation
Sukhoi to Compensate Aeroflot for SSJ-100 Downtime | Business | RIA Novosti
to more serious... here in russian:-
Sukhoi Superjet 100
None of them mention anything about configuration issues, but that could be part of simple disinformation or the start of a deeper media war.
Any dirty tricks are possible with AFL.
