This is THE dealbreaker for me.
I felt so excited to see Plug. I was ready to sign up to Kickstarter to back my first product. It's a plug-and-play NAS, a data solution I've been trying to find. I really, really wanted to use it. But I can't for ethical reasons.
I hate to sound like I'm preaching open-source but it's unacceptable anymore, although I will give them credit that it's a step in the right direction. We need devices like Plug. Just make them open and I'll happily back it.
