I think you underestimate the work it takes to maintain and more importantly grow such a large open source project. If wp engine can barely contribute today, what are the chances they want to take on the whole thing. Nope they just want to get rich off open source. That's understandable , they are a for profit after all. But at what point does it make sense to give back in terms of either money or time to make improvements to the ecosystem that you depend on.
I agree with Matt's ideals but not the actions. The reality is theres not a whole lot he can do without looking like spoilt kid taking his ball away from the game.
I found that I hardly used my nexus 7 and my toddler pretty much made it his own. I use my work MacBook for everything I couldn't or did not want to do on my phone.
At some i began to feel like I needed an in betweeen device and a tablet which is essentially a bigger phone was not the answer. Enter the Asus chronebook flip. Its a thin 10 inch chromebook with a touchscreen that flips all the way around and becomes a tablet. It seems to fill that void. Once Google opens up the ability to install more android apps on chromeos, it will be even more useful.
That definately happens but is an underlying cause. I'm not sure what it is. I've lived in other countries where this natural segregation does not happen.
I would recommend this as well. but i see no reason why this person cannot be your cofounder. If you are building a software based company it would help to have a technical cofounder with a vested interest.
You don't sound like a traditional start-up, so most of the advice form startup school may not apply to you. You probably don't need someone who actually writes code day to day. I would get someone with high level expertise in building and running technical teams who can start from one developer and scale up. That person will lay out your technical infrastructure while you focus on the business side of things. This is definitely not an easy find, and is harder than finding some smart student who wants to play with latest technology x that does not fit well with your business plan.
I quickly browsed the article and I'm not sure how they defined quality. To answer the original question I'd say pick what you're familiar with or what you can easily hire for in your location.
