TBH, security is always dependent on the user later the programmer.. Like take for example Microsoft... It just tries to improve the looks and ease of use of a program for the user and so doesn't usually take into consideration the security factors. One more thing is, I remember seeing a graph about "Security to ease of use".. If you want something very secure, you have to know that you wont be getting the same ease while using that specific thing (a UNIX system probably), and if you want something easy to use, you wont get Secure applications/OS programmed (Windows). Now usually what people would do is just stay at the center of the graph.. Security + Ease of use.. So, there's reduced security which results into breaches. And truth is, laziness is the only thing that makes programmers code with both the things(Sec and Ease) rather that one..
Programmers are after all humans, and till the day humans are lazy, security will be overlooked and only ease of use will be taken into consideration...

Btw, there are paranoids like us who least bother how easy something is to use...
Its kinda late here and am quite sleepy so probably I might have messed up while typing..
