Well if you want to be a startup loyal to your employees you wouldn't back yourself into this kind of corner in the first place, if I was applying for a job at a startup like you mentioned I wouldn't expect much job security and expect to be compensated accordingly.
Well an unrealistic timeline, if your idea is solid enough you shouldn't have to promise the world in a couple of months to get VC backing. There is the slowly building up a startup or leveraging big VC money in an all or nothing approach, one which you don't take if your goal is employee loyalty.
I won't really argue with that - although reality is that the vast majority of startups need to launch fast, or have the entire market move away from them, guaranteeing failure.
If you're developing an innovative product for the iPhone market, you can be sure that it won't be "innovative" in a year, especially if it was a good idea to begin with. Not to mention that in a year, such a fast market will move so far, that your original business model will be outdated in significant ways, because your price point, features, and target audience analysis are now all obsolete.
Even without that, though - you realize that VC-backed startups are a huge chunk of the startup sphere? In fact, the author of this article is a VC, and probably most of this article was written with VC-backed startups in mind.
