Everything I’ve seen from Glenn (to be fair, that's filtered by what his fans make popular on other platforms, because I’m not actively following him) since he shed traditional journalistic standards enforced by editorial oversight at the outlet he founded has been fairly naked ideological hackery that demonstrates why he was wise to establish traditional journalistic standards and editorial oversight when he founded the outlet he left for substack.
Previously his ideological bias was pretty clear, but his journalism was nevertheless, if not flawless, at least recognizable as such. Now he's just throwing red meat to an ideologically-allied fan club
There are however plenty of journalists to carry the established, tired, party line for mock rage and cheap partisanship. You'd be fine with WP, NYT, the Guardian, and many others, there's no shortage of my-party-right-or-wrong types.
Er, no he was very far outside of that (with very much the same ideological bent he has now) even when he was at the Intercept
He votes Democraft (despite being upset at them), is gay, and married to a (male) politician of the Brazillian far-left. (not just "left", his party has "socialist" in the name but has people with strong ties to the communist party and several members openly defend communism).
This model can produce good journalism in some cases (when the people have taste and the journalist doesn't try to optimize his way to placating larger masses) but can also produce bad journalism (say, subscriptions are what sustain all kinds of crap content creators via things like Patreon to Twitch, and hell, OnlyFans).
You're only going to get "good" reporting if it pays well to do so, and pays poorly to do "bad" reporting
