I see the appeal against Wordpress. Wordpress is hell to integrate, slow and a security nightmare. But I don't see the advantage compared to, say Kirby.
There's a post somewhere down below saying smashingmagazine moved to netlify from a Rails, Shopify, Kirby mix[1]. "move would need to include solutions for a decoupled CMS, comments engine, eCommerce platform, and member login."
What Netlify provides, reminds me of what parse used to provide. Except that it adds a CMS and targets Web applications with identity[2] etc. They sell a client facing website platform. Good for them. But that's not what the post is about. So yeah, I do find it misleading.
