News are out that IBM - Lotus is giving away free Lotus Stuff to compete against Sharepoint.

It seems IBM - Lotus wants to forcefully get Sharepoint & Exchange protocols for pennies through the EU antitrust courts.

Seems yet again IBM - Lotus doesn't want to compete in the marketplace on vision, technical merits, features, customer satisfaction or pricing but only using ideology (ABM, Open Source) and general scheming (antitrust lobbying, legal action).

Which is good for Sharepoint customers, partners and MS itself, as it means IBM is desperate and is losing badly vs Sharepoint.
