Still a drop in the bucket compared to WotC's reach and therefore the scope of participants will be different.
The sources you named are those who are in-tune with the greater TTRPG community. WotC can hit people who only worry about D&D. There is overlap, but WotC can hit a larger net. And those people don't have the same opinions as those of us who follow the wider hobby.
My point is that Bob's results should not be used as a replacement for WotC's data, but it will be regardless. All those people who are spreading the word are going to write or vlog expansive analysis when it inevitably shows that people who are in-tune with the wider TTRPG community have strong thoughts on Wizards of the Coast and that will be used to extrapolate that WotC's survey got the same or comparable results and proceed to make dire predictions of doom to fuel the next round of clickbait.
You're going to have to forgive me if I don't take any analysis of this data from you, Bob, or anyone else seriously.
What it might reveal is youtubes opinion on WotC.
Perception can also be reality. Eg if 5.5 underwhelms.......
