Yes JW funerals do not celebrate the life of the deceased, they just promote the jw brand to grieving relatives.
They view it as a time they can blast the none jw's in attendance with a 'witness' - they are utterly pathetic and insensitive even in times of people's mourning.
I was in the JW faith for many many decades, but the most sensitive and enjoyable funeral and wedding services I have ever heard were the ones performed in a 'worldly' environment...
