I really don't think you can mistake a Galaxy for an iPhone when it has "Samsung" written on it right on the front. Anyone who can't tell the difference between the two, isn't in the market for either of them.
Notice something about the scopes of each of those projects?
Same thing with Compiz, a compositing window manager developed by David Reeveman of Novell, also rejected despite it being an almost complete drop in replacement for Metacity which is ancient RedHat technology.
Metacity ancient? What do you make of the whole X server then? Should we replace it too? Don't get me wrong. I don't dismiss Compiz as eye-candy because it's far more than that. It came way to early. It was unusable without proprietary drivers and unstable with. To this day Compiz has problems with stability on anything but maybe Intel boards. The necessary groundwork just isn't there yet.
Losing something and using the court system to get it back can be too expensive for individuals or home-based businesses. SSL is cheaper than a lawyer.
Most data is useless and once it's "out" you won't get it back anyway. I'm talking about using self-signed certificates for data that isn't really worth encrypting in the first place but can act as a tripping alarm or honey pot. Granted you're in deep, if you have to resort to this kind of tactic but it's there if you need it.
With effort, and sometimes a trivial amount, one can invade on another's privacy. But we've all made a social agreement to respect privacy; all it takes is a humble token, like a window curtain, to remind us of this. The curtain is just cloth, but it does an excellent job of affording us privacy, because it asserts our intent. That way, if we're able to detect it, we can be certain in knowing that our privacy is violated -- otherwise, any access we didn't think to deny (but would regret later) might accidentally intrude upon us -- and with no ill will from the innocent onlooker! How foolish of us, that we didn't draw the curtain when we had the chance!
What if the Pentagon is telling the truth and releasing these documents would cause "serious damage to national security" and people die as a result of your decision?
He will be eligible to work there?
Experts in a given field can and often feel that their expertise on a narrow topic carries over to the entirety of human knowledge. People listening to those experts fall into the common trap that their confidence always stems from experience.
Incorporating a "split view" in the default file manager, in my opinion, is an overkill and a symptom of feature creep. I realize KDE strives to give the user freedom of customization but sometimes it introduces needless complexity. Managing layouts is not a job of a file manager.
I'm fond of the traditional UNIX mindset: write a program to do one thing, but do it well. If I need two vertical panes with different directories in it then I fire up two file manager windows and use a window manager with tiling. If I'd have to work with a standard WM I'd just install Midnight Commander or an alternative.
For God's sake, stop researching for a while and begin to think!
