The devs are working hard providing a public service that they make available for everyone. And the product they've developed is pretty impressive, in spite of its shortcomings.

They hold some opinions I disagree with pretty strongly, and I'm not a fan of every decision they make. But they're creating a truly common good, and for that they deserve praise. From a technical perspective, they have created something completely new that serves thousands of users and constitutes a system of huge complexity. They very much do not suck.

Anyone who thinks any person maintaining an open source project "sucks" should feel free to fork the project, fix whatever they're not happy with, and maintain the repository and handle commits and all the shit that goes down in managing a large open source project. After dedicating all this time to people, some random ingrate will inevitably disagree with some minor decision they've made and decide that they "suck".
