Interesting. OS business -- licensed and then bought an OS and then re-licensed it out. Eventually had to use illegal anti-competitive tactics to stave off competition.
Browser business -- Licensed and then gave away a browser (and was sued and had to pay the company that owned the browser). IIRC, IE7 was the first Microsoft-only browser. Also eventually had to use illegal anti-competitive tactics to stave off competition.
Word processor -- That was actually their own, designed originally for the Xenix (UNIX) operating system. The jury's still out on whether Microsoft used the transition to Windows to kill off WordPerfect through keeping certain Windows programming information from WordPerfect's developers.
You must be new to this world, since, major corporations, expand through purchases and/or mergers. Microsoft does it, Apple does it, Google does it, IBM does it, as well as many others.
However, when it comes to playing nice, Microsoft does exactly what Google and Apple and a lot of other companies do and have done in the past.
In the area of copying and/or stealing, again, there isn’t a company out there that is not guilty of doing that.
On the other hand, Microsoft spends more in research and development than Google or Apple, and, thus, end up with a lot more products and services than the other two combined. In fact, Apple is very far behind Microsoft in the number of products and services they offer, and, btw, so is Google. Perhaps Apple and Google need to start doing more R&D, and start being more creative.
So, did you have any real points in your comments, because, as far as I could tell, what you posted is part of the past. Dwelling on the past, and not looking at the present with a clearer vision, is going to keep you bitter.
