Remember the very recent discussion about IE8, its new engine, and possible plans to extend ('proprietaise') the Web further? Well, here is a timely update on this issue. Opera has just filed a lawsuit.

Opera Software has filed an antitrust suit against Microsoft in the European Union, accusing it of stifling competition by tying its Internet Explorer web browser to Windows.

The complaint, which was filed by the Norwegian firm with the European Commission yesterday, says Microsoft is abusing its dominant position in the desktop PC market by offering only Internet Explorer as a standard part of Windows, and hindering interoperability by not following accepted standards with IE.

Opera is asking the Commission, the executive branch of the European Union, to force Microsoft to unbundle IE from Windows, or include other browsers as a standard part of its operating system. It also wants it to require Microsoft to adhere to industry standards with its Web browser.

It's something for the ISO to watch, just in case it intends to allow Microsoft to continue treating documents standards like it treats Web standard. ⬆
