I've just heard of Substack, what's wrong with it?

Do you mean x.com? Because someone registered the expired Twitter name and is building Twitter.now as a replacement for What the old Twitter became.

Oh, majority are Nazis..

I haven't used substack, but I've never heard any negative discourse about it either. A lot of Nazis on there I guess?

I'm curious too, is this about the owners or the writers?

Yeah but it's just another corpo take. They basically came right out and said we got investors, we got a business plan, we wanna make some money.

I don't know much about Substack, but there are some killer blogs there. For example Kareem Abdul-Jabbar's.

Suppose I've heard a lot of talk trashing Substack, but what alternatives exist?

As a non-user who doesn't do much of anything in that space, seems like they're one of the few ways to distribute newsletters and such to emails en masse.

Nothing as far as I know. It has some of the most thoughtful news / opinion channels I've read. But OP seems to hate it per their bio.

Substack faced further criticism in November 2023 for allowing its platform to be used by white nationalists, Nazis, and antisemites.[61] In an open letter, more than 100 Substack creators threatened to leave the platform[62] and implored Substack's leadership to stop giving bigotry a platform.[63] In response, Substack co-founder Hamish McKenzie said the company would continue to allow the publication of extremist views because attempting to censor them would make the problem worse.[11][64]

From their Wikipedia page

The CEO did an interview on The Verge with Nilay Patel and refused to say that he would take Nazi content off the platform, taking an 'absolute free-speech, nothing is censored' approach.

The common sentiment is that refusing to take down Nazi content makes one complicit and supportive of Nazis.

But I have no idea how many nazis post on Substack.

No tolerance for intolerance is a principle which he seems to be whiffing on. Or maybe it's as simple as significantly more profit for him by turning a blind eye.

Substack has a Nazi problem

The newsletter-hosting site Substack advertises itself as the last, best hope for civility on the internet—and aspires to a bigger role in politics in 2024. But just beneath the surface, the platform has become a home and propagator of white supremacy and anti-Semitism. Substack has not only been hosting writers who post overtly Nazi rhetoric on the platform; it profits from many of them.

In addition to what others have posted, there was also the time they "accidentally" sent a push notification promoting an actual Nazi blog, swastika amf everything.

Other options include Ghost, Beehiv, Wordpress, Blogger, self-publishing, on and on. Nobody's forced to hang out with Nazis; it's a choice.
