Controversies

 * RedOS 4 was replaced by RedOS 3.5:

This controversy does not apply to RedOS in general, but applied to RedOS 4, which was criticized for an absurdist reason, due to fear of the number 4. This version had been withdrawn and replaced by RedOS 3.5, which is supposed to have the same functions as RedOS 4.
