Personally my issue isn't that Josh doesn't have a point but that he put his foot in his mouth by even talking about doing this at all. After all, he does have a point. Remember what the "HE WILL NOT DIVIDE US" flag saga proved:
And that's just one thread. There's tons of examples of this kind of super investigative autism, a lot of it even being on this site (without harassment or etc.). Body language, room design, lighting, background noise, window placement and sun movement, etc. Literally
anything can clue enough autists into where you are, and Josh has good reason to respect the danger of that, particularly when he's not just observed by autists but litigious and malicious lunatics like Vordrak.
Josh could end up with a broken life just because he posted a picture of himself where the sun glinted at a certain angle of the obscure wallpaper that's only ever used in X region of X country by X building planners.
HOWEVER
That's why our doggo leader should never have mentioned a competition of any kind. I was shocked it ever entered his mind to do such a thing considering the numerous beady eyes perpetually on him. Further--and this is the real problem--if I recall correctly (and you can correct me if I'm wrong) he even stated that he had "mentally prepared" himself for following through with a picture for the Ralph competition. He said that if he could wear a mask and MAGA hat or something he would go through with it. He also said that he fully suspected Ralph to renege or cheat the minute he got a picture of Null, and he was prepared for that outcome too. This was on his MATI podcast stream, and its where PPP seemingly got his retort about "Josh doesn't want to do anything fun", because it's what he had said about Ralph.
Then Ralph turns out to be a dog killer and Josh retracts his competition idea. Good on him.
But then PPP decides he wants to do a goofy competition with Null and Null completely rescinds his previous compromise he was willing to make for Ralph.
I get why he'd rescind, because whatever fun pics are posted between the fun with him and PPP, those pics will be public and therefore become content for GUNT FEEDER, THE DOG EATER. Null doesn't want to inadvertently give Ralph content. However, Null already has given him content by mentioning this idea to begin with and then backing out with PPP. Yes, his offer was prior to Ralph being outed as a dog killer but it was not prior to literally everything else we know about Ralph. Null knew better. Now it just gives the same vibes that Chaggot gave when he refused to arm wrestle Baked and decided to get slapped instead, thinking that was the more dignified outcome. The better choice was never to start this in the first place.
Of course the alternative is that Null always intended to back out as part of a bigger plan. He made the competition offer for Ralph only because he already knew he had the dog dirt on him. He planned on exposing Ralph's animal cruelty and backing out in order to make himself look good and emphasize Ralph's psychopathy. Everything was going exactly as Josh planned until PPP comes bullrushing in with a cheeky grin shouting about having fun together, unwittingly ruining Null's Light Yagami moment.
I don't think this is the case since I doubt Null is a Dark Tetrad. But what do I know? I don't even play Smash.
TL;DR If you're living like you're in Witness Protection don't volunteer to put yourself in the spotlight. I respect our doggo leader's decision but the jokes are well earned since he never should've started this considering his perpetual danger.
