What is his moral objection to Jews
That they've occupied a massively disproportionate share of elite influential positions in western societies for a long time and have used their influence to drive white societies to ruin via a number of means, not the least of which is mass immigration. They can do this because of the shield that is the accusation of anti-Semitism, which prevents people from identifying and stopping their ethnic power bloc shenanigans. I'm not sure he would even couch this as a "moral objection", it's just a fucking fact and as a white man it's been bad for his race and society so obviously it's against his interests.
That they're obviously not women but try to force all of us to pretend like they're women and actively put themselves in positions to directly influence children. Do you think he would support a mass movement of lolicons demanding that they not be discriminated against and allowed to openly be teachers in kindergartens and grade schools and, like the trannies have shit like Drag Queen Story Hour, have public institutions such as libraries host Lolicon Story Hour? Why don't you ask him that?
when he gets so angry at the suggestion he should purge 1/3 of his stream audience for being lolicons, because he would lose money? Or when claiming that if someone's a pedo it's none of his business?
He has never claimed to be a moral paragon or a crusader of morality. He simply can't help but say what he thinks about the reality presented to him, which, in our time and place, makes you a Nazi by default. That does not mean he is a valiant paladin knight crusader. It means he's a man that can't stop himself from saying that the emperor has no clothes.
And him wanting to make money off the lolicons does not make him a grifter. Grifting is not just making money, grifting is being intentionally dishonest in the pursuit of making money, it's running schemes or scams, at the furthest extent, it's pretending you're interested in something you don't give a shit about, or lying to make money, or pretending a piece of shit game is great to pander to the many casuals and normalfags that like the shitty game so that they'll give you money for agreeing with them. He simply doesn't care about the lolicons and is fine with taking their superchat money. That's not grifting, that's apathy.
What value does him accusing other people of being "controlled opposition" and "grifters" hold at that point?
His reason for calling people like Mauler, or Worth a Buy, or Almighty Loli grifters and controlled opposition isn't because they aren't moral paragons and Eastern Orthodox tradcon tradcaths tradwife tradie trad trads. He labels them grifters because they lie and obfuscate about the leftist political motivations behind wokery in videogames while also accepting and praising mediocre gameplay, mediocre and shitty writing, etc. He calls them grifters because they LIE about the topics they cover, or because they're simply too STUPID to recognize the obvious truth in front of them, not because Synth considers himself some great moral guy. He's a fucking 4chan agnostic edgelord shut-in NEET.
This is fucking retarded.
