While the details of this 'Mormon' "apostate's" grievances are pretty tame compared to JWs, there are some similarities. However in one aspect the LDS we're better than JWs.
"The issue is not that you have concerns -- or even that you disagree with the Church's guidelines, rather it is your persistent, aggressive effort to persuade others to your point of view by repeatedly and deliberately attacking and publicly opposing the Church and its leaders," the church's excommunication edict says.
Notice it was okay for him to disagree and even talk about his differences, just not oppose the leadership to the degree he was. JWs however have published that even harbouring personal thoughts and opinions that differ from official dogma could be "apostacy".
