The real problem with the Me 262 was not Hitler so much as it was Junkers could not make the engines fast enough. And the engines they did make only had a service life of about 10 hours or so. This was due mainly to the lack of critical metals, like nickel, chromium and molybdenum that were needed to make the heat resistant metals needed to make jet engines.
Messerschmit had produced hundreds of airframes that sat idle for lack of jet engines. And those engines that were made were also used by the Arado 234 jet bomber.

Even when the Luftwaffe had the 262’s they lacked the fuel to fly them.
Again Hitler screwed his people by fighting on multiple fronts.
