Just because it's a tactic used by shills doesn't mean whenever the point is made it's shilling / irrelevant.
Sometimes it's actually worthwhile to point out when an instance of behavior is actually part of a much larger, much bigger problem.
The argument is akin to saying "what about the Sackler family" in response to a criticism of Theranos, as though that somehow vindicates Theranos.
At best, you're suggesting the "everyone's doing it" defense applies in this case. If a cop won't let you out of a speeding ticket because others, too, were speeding, then why should we let the poop-testing startup off the hook because other crimes have also been committed in the same broken system?
> I don’t think the alleged crimes committed by them or Theranos are nearly as bad as the ones committed by big pharma and uspto and the rest of the healthcare industry
This pivot is why, I presume, there was an initial response that touched on whataboutism.
