Update at foot of post.
Microsoft and “several other firms” have reportedly lodged a formal complaint to EU antitrust regulators about Google+, the Internet giant’s social networking tool.
Whilst the European Commission hasn’t confirmed this, and Microsoft has declined to comment saying that it wouldn’t issue a statement on “rumors or speculation”, this is a significant move if it proves true and will serve to heighten tensions between the two companies which have been escalating over recent months.
Whilst this led to a series of public retaliations between the two companies, if the Redmond-based company has lodged a formal complaint against Google overs its social network, this would certainly takes things to the next level.
Update: Speaking to ZDnet, Microsoft has denied being part of any antitrust complaint related to Google+. However, that does not discount the possibility of Reuters being partially right, and others being involved in a complaint.
