There are two separate things being discussed here, as @deanius says, “Technology” and “Governance” (AKA MDG’s relationship to the community).
Technology
The original post was, to paraphrase, “now that more solutions exist for some of the problems that Meteor solves, do we still need Meteor?”.
I like @joshowens’ answer to that one:
This is exactly why I use Meteor, and it’s no less true than it was 2 years ago. MDG has described their goal as being to package the best JS technologies together in a way that makes it easy to use for developers, and this will continue to add value for as long as they continue to do a good job with it.
I want to build apps as quickly as possible. I also like to explore new tools and I won’t be satisfied if I’m not using the best tools, but at the end of the day I send invoices to clients and more than ever in my career I see the value of building good things quickly. Does webpack help the average Meteor developer here? I want more than a hammer in my toolbox, but I don’t want to have to build the whole workshop myself. This is the value that Ubuntu provides over compiling your own Linux kernel and gnu tools.
I think MDG is way ahead of the curve on making a cohesive package of the best JS tools, and the proof is that most Meteor developers will be using (most of) ES2015 before the end of this year. Compare that to the average.
If I thought webpack provided some huge benefit I’d be figuring out what it would take to refactor Meteor to use it, and either submit a PR or organize a community project to do so if it’s too big for me.
Governance
The second discussion is about the Meteor community, and whether MDG is “listening to the community". One of the things that MDG has done better than any other open-source project that I’ve ever seen is organize community. Sure it took a while to move to Discourse, but here we are.
They brought us all together, but now that we’re here they can’t please all of us all the time. They can’t maintain clear focus and also take everyone’s input (and PRs), even if they had the time. But also you can’t rule an open-source project with an iron fist and MDG knows that. I hope they continue to value the early and largest supporters like @arunoda / Kadira etc.
But most importantly, Meteor is an open source project, and that means you can do what you want with it. The fork discussion is inevitable in any large open-source project, and isn’t necessarily a bad thing. It helped Node and Rails too (OK Merb wasn’t a technical fork, but it was a division of the community that came back together for the benefit of all).
Don’t sit back and complain about the direction of the boat. Help steer.
