Its not the cost of BGA rework hardware alone that was the main barrier back then, it was knowledge and experience. BGA was seen as something very difficult to the point of not being worth even attempting. In early 2000 even basic SMD was an insurmountable barrier to most amateurs, today its trivial despite using same equipment. Op author Markus Gaasedelen identifies himself as a software researcher by trade, but casually replaces BGA CPUs on the side :) all thanks to easier access to information. Merely knowing something is possible pushes humans forward, thousands of available tutorial pages/videos helps too :)
