You're right that it isn't out of hostility. They've made that clear. I don't know if the reality is better or worse though. The reality is that they supposedly want to support Linux, but they are willing to make changes that mean it doesn't work, and they aren't going to be upfront about it.
Embark has done a great job ensuring Linux compatibility isn't broken ever since they said they'd work on it. They've been pretty forward about it. I'm thinking that also might be why Elytra isn't enabled for them yet. It's not compatible with Linux, so they're holding off. Wardogs though? They're going ahead with it, then saying the Linux community made a mistake rather than them. For them, this isn't a mistake. We just need to be patient for some future date that isn't given.
The issue is that Linux seems to consistently be an afterthought for them. They say they care about Linux support, but they aren't acting like it.
