That's essentially a rewording of the above claim and again without evidence.
In fact, it's detrimental for the perpetrators of disruptive actions to attract attention to them/selves when these actions don't achieve their purported benefits.
If they wanted only to simulate activity, they'd have used less damaging to themselves ways to achieve it without inflicting damage to the system. The latter is so important that it excludes accidental or PR-related actions to that end.
maybe disrupting things badly is more preferable as that gets more attention, but ultimately the impact is good or bad doesn't matter at all.
