I am a PhD student collaborating with a professor (not my advisor). I did the work while the professor came up with the idea and funded the project. The research project centered on an experiment.
Initial experimental results were consistent with Theory A, but they could (with some stretch of the imagination) be consistent with Theory B. Theory B, if proven, would result in a much higher scientific impact.
The professor then decided to conduct a followup experiment. His intention was to provide more support for Theory B. The professor was very excited about the followup experiment, but all the results of the followup turned out to be inconsistent with Theory B. When I updated the manuscript with the the new results, the professor's reply was very brief: "I won't be including results from the followup experiment because I don't have time to look at them". However, he took the time to make further edits to the previous version of the manuscript (with only the original experiment inside) to present the results in a manner such that the original experiment appeared to support Theory B.
The professor then sent the manuscript to me and asked me if I had any comments before he submitted it to a journal. I protested, but the professor told me that he is the owner of the project as he came up with the idea and funded the experiment. I was told that I can either have the name on the paper, or withdraw completely and irrevocably.
I do not think this is fair. Is it reasonable of me to say that I do not want my name on the paper now, but I might want my name on the paper in future if the results are (in my opinion) honestly presented?
