AFAIK a fundamental step in any quantum computing algorithm is bringing the qubits back to a state with a nonrandom outcome (specifically, the answer to the problem being solved). Thus a "good" quantum computer does not bifurcate the wavefunction at a macro level, ie there is no splitting of the "multiverse" after the calculation.
I think they are arguing against the subtitle of the article:
"Recognizing that mitochondria are alive will open new horizons into how we learn about, and build with, biology."
Which seems a stretch based on semantics.
Perhaps one can debate whether it happens often enough or severely enough, but it certainly happens. For example, and only the first one to come to mind - the president of PIP went to jail.
