...saw a PMs from forum members about this story...
I'm a fan of full disclosure so I'll admit that was me. Chain of events on my part were not unlike btarunr's:
1) Saw Reddit post and read it.
2) Noticed it was 12 days old and questioned why no one was talking about this.
3) Sent PM to btarunr.
4) After I sent the PM, I thought, "hey, I can verify some of this myself!"
5) Pulled up DuckDuckGo.
6) Did a search for RX 5700 XT
7) Changed to "Video" tab.
8) Started watching the first video listed (Oct 25), waited for the first panned out shot, paused it, took a screen shot, scanned for RTX product placement. Highlighted it and edited it into my initial PM with btarunr.
9) Started watching the second video listed (Oct 19), waited for the first panned out shot, paused it, took a screen shot, and scanned for RTX product placement. Highlighted it and sent a second PM because the 5 minute edit window closed on the first PM.
I went to bed at this point and btarunr took it from there. My hasty research undeniably mislead btarunr and I profusely apologize for that. My intent wasn't to accuse any YouTuber of anything. My intent was to give some attention to this claim that has largely gone ignored which, at face value, appears to have some credibility.
I am not the whistleblower nor do I know the identify of the whistleblower. I am just a messenger, like btarunr.
