This is a very unfortunate state of affairs for science in general, giving the amount of tools we have to make an experiment more replicable.
Replication is perhaps simplest in the field of computer science, yet many papers do not release the associated source code and configuration used in experiments. It's very easy to make the code available to all so I find it a bit dishonest and unscientific not to share an experiment.
There may be other things at play which prevent methodology being fully shared, it may get too personal, for example experimental code is sometimes developed quickly, and people may be reluctant to share their own messy code for fear it might reflect badly.
