Good God! You've got a real M$ axe to grind, haven't you?
>DOS : bought for 20000$USD when it was still called dirty operating system
Yep, the somewhat tiny MS of the time bought 86-DOS (aka QDOS, or Quick and Dirty Operating System) from Seattle Computer Products (which was a rip-off of Gary Kildall's CP/M). They modified it to meet the requirements of their then customer, IBM, and released it as MSDOS. IBM also produced a modified version, known as PCDOS. I'll grant that this was because Bill Gates couldn't actually deliver his own OS in time, but how this counts as 'copying', I don't begin to understand
>Windows 1.0 : copied Xerox
I wish! Amongst other things it lacked icons, and overlapping windows, and initially was limited to CGA resolutions.
That being said, Apple released their 'rip-off' of ideas from the Xerox Alto/Star , the Lisa, in 1983 (Xerox sued Apple in 1989. And when did M$ announce that they were going to do their own GUI for the PC? Yep, 1983. So, who do you think they actually copied (badly)?
>Windows 95 : blatently copied Macintosh (recycle bin, desktop that all comes from Apple).
It is a fair point to say that MS didn't originate the some of the ideas in the W95 desktop. However, much of the Mac GUI was a blatant copy of, or derived from, ideas developed at Xerox. But then so is Ethernet, and we don't go around accusing people like 3COM of copying.
>Windows NT : copied kernel and many subroutines from Freebsd
Impressive. FreeBSD v1.0 wasn't actually available until December 1993, and NT 3.1 was released in August of that year (and had been first demod back in 1991), and the design team got together in 1988 which is a whole 2 to 3 years before BSD was ported to the x86 environment. Given the above I'd question your assertion.
>Word, Excel, Powepoint : Word copied a Mac program whose name I forget. Excel is a copy of Lotus 123, Powerpoint copied Harvard Graphics.
Microsoft's first spreadsheet was Multiplan, which predates Lotus 123. Microsoft would argue that Excel was a derivative of Multiplan. Furthermore, Word was originally designed to use the same UI as Multiplan. Since this version of Word was originally released several months before the first Mac, it would make if difficult for it to be a copy of a Mac program. I should also point out that Lotus 123 was a blatant rip-off of VisiCalc. As for Powerpoint - well, the first versions were black-and-white only Mac releases. And it wan't developed in-house. Forethought Inc. developed it in about 1985. MS bought it from them after two years of wrangling, and released it as Powerpoint 1.0 in September 1987. The first version of Harvard Graphics was released in 1986, so Forethough sure as heck can't have been copying it in 1985...
>Frontpage : failed attempt to copy Dreamweaver
Or possibly any other number of HTML editing packages.
>Visio : bought from another company and then recoded to work with Office.
So?
>Windows XP : some of the bugs found in Freebsd are also found in XP. This leads to think that XP uses lots of C routines found in FreeBSD
Is this your sole tenuous basis for arguing that NT is based on FreeBSD? Oh dear.
>Internet Explorer : some parts are Based on NCSA Mosaic. RSA code copyright of RSA
Many early browsers were based on Mosaic, including Netscape's. And ANYONE using RSA has to licence it.
>ActiveX : nothing more than a Java clone that only works with Windows
<sigh>. ActiveX (which really just a marketing rebranding of OLE and COM) is partially derived from IBM technology that MS had access to when working on OS/2, and (as OLE 1.0 and COM) predates Java's 1995 release by at least 4 years.
>JScript : copy of Netscape's javascript
JScript is an implementation of ECMA-262
>MSN Hotmail : bought for a few millions
Rather a lot more than that. But I don't understand the point you are making here.
