I don't see how this is a counterargument, or highlighting any fallacy. The article talks about hacks used to get around garbage collection in Java and increase performance, including memory mapped files and byte buffers. It also talks about the pain points of using these hacks and the costs they have to pay despite these hacks. It also concludes that it is practical to build Git in a higher level language and JGit performs reasonably well, despite not getting quite C level performance or its memory utilization.
