Mediatech guy for a university in Germany here. The reason for that is that the average lifetime for installation projectors is something between 8 and 12 years, after that either the power supply dies or it gets hard finding light fixtures.
Either way most universities only feel compelled to spend money when something breaks. I wish that was different, as it makes my job very stressful at times, especially when multiple things break within a small time span.
