It's likely a mixed bag. If you're diligent about which organizations you choose to support, you're more likely to have a positive impact.

If you want a simpler example that doesn't involve biotech research, I would just look at the diversity of animal welfare organizations, and their relative quality. Some of the best animal welfare organizations in terms of impact are local rescues run by (in my experience) spouses of wealthy career-people (executives, lawyers, etc.) who have a ton of free time and love animals. But then there are also plenty of animal welfare organizations with questionable motives, and questionable spending patterns - bordering on fraud and embezzlement, if not outright fraud and embezzlement.
