Why

Once upon a time I bought a HIFI. It came in one self-contained box and had a record player, a cassette deck and a radio tuner. I took it home, put it on the sideboard, plugged in the speakers and the aerial (A piece of wire that I put up on the wall with drawing pins), plugged it into the mains and turned it on. It worked first time and continued to work faultlessly for the next five years until the cassette deck finally gave up the ghost. The question is: Why isn't all technology like that? Why do we have updates and need protection from spam, malware and spyware and viruses? Why do Microsoft sell something as basic as a word-processor but make it so overloaded with bloatware that it strains the memory and processor of even the newest computer? Why? Why? Why!!!
