I am totally fine with Jones doing whatever in his life. Picograms, drugs, beating his pregnant wife. f'ing off etc. It is his life so he can do whatever. Karma comes knocking on everyone's door.
My big issue with him is deliberately trying to sabotage Aspinall's career by holding the belt hostage and having Dana White in his pocket (not stripping him). Aspinall is wasting his prime years. Everyone knows Aspinall is going to give Jones a beating of a lifetime. Jones said it himself in that congratulations etc. message.
Aspinall needs to be the heavyweight champion and be the face of UFC now, but Jones is purposely trying to sabotage it so that he could let Aspinall waste his prime years away and that will reduce probability of Jones' legacy being overshadowed by domination of Aspinall.
