Writers that take over another writer's universe

I abhor this practice and this guy sums my thoughts up perfectly: "Brian Herbert has not just tarnished his father's legacy, he has ridden atop a burning money train straight down the gullet of his father's dessicated corpse, exploding it in a shower of creepy sex scenes and lame multi-page descriptions of giant robots fighting. Burn in hell forever, Brian Herbert. I hope you slip and fall in that new bathroom."
