I have not read anyone claim that SynthID had a false alarm issue, so if it returned positive I would believe it is synthetic.

You can trivially false-flag any image by uploading it to gemini and asking it to return it as-is

		That's not what the previous comment is referring to. They're referring to false positives, i.e "Gemini did not generate this (or process it) yet it says SynthID confirmed"
