Let me preface this tirade with a disclaimer: Yes, I realize Microsoft is a huge company, with enough resources and market share to constitute a monopoly, and is therefore deserving of governments' watchful eyes. I also realize that IE may not be the highest quality browser out there; and that Microsoft has been known to 'embrace and extinguish'. I'm also glad that Microsoft didn't get to design (for instance) the IMAP RFC. Please note I'm not making any _legal_ arguments, just "history-of-OS" type arguments.
HOWEVER, this knee-jerk reaction to the browser-wars is really fundamentally flawed. My argument is what we, the user, perceive as an operating system changes and grows over time. I think it's time we realize that a music jukebox, dvd player, web browser, and text editor have become integral parts of an OS (per my definition). I think it is in the same manner as a command shell, file browser (cd & ls), calendar, chat client, windowing system, network stack, etc. have become what we'd consider part of an OS.
Some companies and organizations are clamoring for inclusion of their pet projects by default... I say "rubbish. You might as well ask the user to choose different versions of the TCP stack, paint program, image libraries, and mouse drivers too." I can't make any analogies to car makers, nor do I care to. We can argue about "stifling innovation and choice" until we're blue in the face, but I still insist that a web browser is integral to the operating system. Go and get alternatives if you like, just as you're free to get another media player, paint program or ftp client.
I don't see noise directed against Apple or Linux or BSD, likely because they are {not monopolies | high enough in market share | something else that I can't grok}. This would suggest that the bundling of Safari on Mac, or Mozilla on Linux is not fundamentally wrong, and is also not wrong on Windows. I'm sure there are good arguments for the EU poking its nose, but since they're so caring, they should also ask nicely that MS provide users with choice of desktop clock widgets so that the poor makers of clock software aren't left out.
Perhaps this is unfair to the hapless (as far as tech goes) politicians, but they seem little more than shills for lobbyists, and don't seem to really understand the dangerous precedent they might be setting. That, I find really irritating.
