There are downsides to him releasing complete tax returns since they allow competitors access to info about how he structures his businesses that would allow them to target weak points. That would be irresponsible for him to allow since so many employees & investors could be affected.

It is doubtful that much of strategic value is contained in his personal returns. The valuable stuff for competitors would be in the corporate or partnership returns and even then, there is little there that couldn't be obtained from other sources. I don't believe that anyone is calling for the release of those returns.
