The peer review system is definitely biased. It's ok for many articles, but there are outliers. For instance really original theories or experimental data. The publication may be stopped to avoid putting the journal's reputation at risk or because the reviewers have personal reasons to not support the article (it would shade their own pet theory, invalidate their research project, they didn't understood it, etc.).

The problem with publishing elsewhere is that many people unable to objectively evaluate the validity of the theory juge its value by the reputation of the journal. Also the other journal will most probably have less visibility. There is thus a higher chance that the other theory will not be reported in reviews.

There are many assumptions in the above comment that I can't agree with. But my experience is with physics, not computer science.
