Hardly. Hamza has been praised when he's deserved it (the WBA home game in the Championship a few years ago for example) but has been slated at other times. His off-field issues do not help his cause either. He's a limited player technically and always has been, so not much has changed in that respect.
Other youngsters who have come through the ranks have also merited criticism at times - Chilwell being a prime example for his defensive lapses and being bang average going forward; Barnes for his lack of tracking back; Schlupp for being a poor decision maker. However they have also been supported plenty of times. Andy King is a prime example of being an academy graduate where your theory is completely discredited because he was always supported.
