You can do a "study" to prove anything you want. And study outcomes often do vary depending on who is paying for it. The FDA is a neutral party. I recommend prioritizing the FDA warnings over "studies".
The FDA errs on the side of placing more warnings rather than fewer. They'd rather have false positives than false negatives. The warning is also clear that there is not a definitive causal link.
If you want to trust individual anecdotes over RCTs while scare quoting the primary way we advance science in these fields, be my guest.
