Hey, MS during it's life has
1) reformed DOS to stop lotus running
2) reformed Windows3x so that DR DOS looks to be failing
3) reformed Win9x so that Word Perfect breaks
4) reformed CIFS/SMB so that only windows can serve windows
5) reformed windows so that Netscape dies
6) reformed OEM contracts so that BeOS dies
7) reformed EULAs so that you no longer own your software
8) reformed Windows so that you no longer own your computer
9) lied in court about IE bundling
10) lied in court about trademarks (Lindows!=Windows)
11) reformed licensing so that they can extract more money from the customer
12) managed to do all this without losing all their csutomers
Now, what can let MS do that? A monopoly. This allows them to reform the market to suit THEIR needs and not serve the needs of the customer.
Because of this, ALL customers (whether of MS products or not: if you need to read a .doc file, you need to either lose interoperability or buy MS Word) are harmed. You can't jail a corporation, you can no longer remove their corporate charter nor can you remove their copyrights and patents. Governments cannot move from MS because the US justice department or diplomatic corps will put pressure to bear on you to "not discriminate (unless it's FOR MS products)". The only way to punish corporations is to fine them and KEEP fining them until they either die naturally or change their ways.
As to MS being an easy target, maybe that's because they SHOULD be targets? Kiddie-fiddlers are easy targets. Does that mean we shouldn't prosecure them? No, because they are rightly easy targets.
How can we say we lost X money from MS's practice? Easy: the same way as the RIAA know they lost trillions to piracy. If we didn't have to buy Vista or Word 2007 and could stay on 2000/XP and Word98, we would have all the computing ability our desktop needs and we would be richer by whatever Vista/Office2007 cost.
Windows Media Player isn't a problem on its own. That it is ONLY on Windows AND that it is the only player of the propriatory codec MS uses is the problem. Either open up the media format or remove it from the default install (WMP doesn't come with Theora playback, not even MPEG2 playback, so why must it come with WMA?). MacOS doesn't have the market leverage to make Quicktime8 (or whatever) the indistry defacto standard and Linux only has open codecs that anyone can implement, so Mac's are OK because they have no leevrage and Linux is OK because there's no format to leverage.
Also, for some reason people seem to have forgotten that when Macs came with Safari as a default (but removable, unlike IE) browser, MS withdrew IE for Mac. Why? (and this is a killer!) Because they cannot compete with a browser that comes with the OS! Ha! I thought that knowing there were alternatives was good enough! Or is it only good enough when it ISN'T IE?
