I'm not sure it's worth responding to the OP's shouty rant but for the sake of putting the relevant history on the record here goes.
In 50Hz countries film (24fps) has nearly always been shown on TV at 25fps. Nice simple solution whose only side effects are a 4% shortened runnng time (eg a 100 minute feature would last 96 minutes) and sound pitch raised by 4%. That's just over half a semitone, inaudible to most. Sometimes the pitch shift was corrected using pitch shifting techniques. Unlike 3:2 pulldown used in 60Hz countries there are no problems with juddery motion.
Until framestore and interpolation technology became advanced enough to accurately convert 24Hz to 25 or 30 it wasn't really possible to do any better. For the purists I'll mention the Mechau variable speed system which did a sort of optical interpolation but was never very satisfactory. You could also run film at the correct speed on a vidicon telecine, relying on the laggy tubes to get reduce the beat between film and TV frame rates. Again less than satisfactory.
