Rude computer programs

One thing I have to say, is that most computer software, especially in windows, are designed to be rude in the start up phase. Let me explain
Everytime I start up my computer, there is some programs that is set to run on start up. These all pop up to the middle of the screen as soon as they are initialised to "tell"  you something or to be ready for you to use. They all pop up to the forefront OVER applications you might be using, proudly announcing their arrival. This is a source of annoyance to the nth degree.
And software you initiate manually is no better. developers all assume their software is the most important on my computer and that when I initiate their software, I will use their software solely and every other program I am working with must take a backdrop. How insanely rude. Why not write the software to nicely open up to the taskbar? I am busy typing in my word processor, I in the meantime open FireFox, Firefox pops up and sets itself in my face taking over my screen and the last few letters I typed in my word processor is missing. If that is not annoying then I dont know.
Gnome 3 has a very nice feature where it gives a tiny pop up at the bottom of the screen informing you that some program you opened is ready for use. Nice Linux, one up for you.
To all you software developers out there, please please please do not assume that your software, called upon is the one most  important sole thing on my computer at that point in time. Rather make it start up to taskbar.
