Because the JVM developers had customers who asked for the ability to tune the GC for their particular application.
Go will receive those feature requests too. The Go developers may not be as willing to provide so many knobs (which is a position I'm entirely sympathetic to, don't get me wrong). But the settings always exist, regardless of whether Google hammers in values for them or leaves them adjustable. GC is full of tradeoffs; they're fundamental to the problem.
