Microsoft or COPYCAT

Microft the world’s largest software company aint it ???
But what the other side of mirror says:
Each and everything which Microsoft has released is a copy of some other less famous product.
Some examples:
Word from Word Star/ Word Perfect
Access from Foxpro
Win95 from Mac84
System Restore(the latest from WinME) is just the copy of Acer Time Machine Technology
There is nothing which is solely their.
The monoply is incresing day by day . . . .

What is your view.
