These writers are steeling material from authors like Harlan Ellison, D.C. Fontana and others without giving them credit. This fact cannot be disputed.
It could be argued that, since the previous shows and novels and whatnot are all under the same legal ownership, it’s technically not stealing.
But, as can be seen throughout the franchise’s history, there have always been credits or acknowledgments when necessary, be they in-house (such as the repurposed PHASE II scripts that ended up being used for TNG), or to avoid potential lawsuits (like how the rights to Fredric Brown’s short story, “Arena”, were secured after someone realized that Gene Coon’s script for “Arena” may have been unintentionally influenced by that story, or was at least similar enough to potentially cause a problem).
And, as per standard procedure, even STAR TREK- THE MOTION PICTURE has the “Based Upon STAR TREK Created By Gene Roddenberry” credit, despite the fact that Roddenberry himself produced and co-wrote the film.
But, as we all know, plagiarism and rehashing the ideas and characters of better and more talented people is standard procedure for Bad Reboot and Secret Hideout. The idea of giving proper credit is as much of a joke to them as actually doing justice to past writers, actors, stories, and characters. They steal, throw things into a blender, and paint the nonsensical and dumbed-down results with an expensive topcoat to disguise the appalling quality of the writing and storytelling.
