How do you check your own aircraft to confirm it is operating correctly?
Has that been done?
Don't rely on a crowd-driven, cloud system for accurate position information.
Just because your phone says it was so, does not make it so.
If ATC can't get accurate data with SSR or ground stations, then it's not worthy as a basis for a fictional opinion.
