Are you aware Microsoft was punishing OEMs for using Netscape internally? And punishing them if they shipped Netscape (while still keeping IE) and letting the user choose? These punishments over time helped lead the OEM into ruin in the end. An OEM with one of the highest customer satisfaction scores in the industry back then.

And the IE situation was looked into mostly due to Microsoft being fined for forcing OEMs to buy a copy of Windows for every machine shipped. Including the ones that shipped without Windows back when OS choice existed in the early 90s. These actions led to Windows becoming a monopoly, thus putting Microsoft under some different rules to prevent monopoly abuse. Their actions with IE were illegal under both US and EU laws.

Ridiculous is also something I'd use to describe it, but aimed at Microsoft, not the US DOJ and EU for investigating.

Google has similar ridiculous agreements and punishments they have pushed on some OEMs when it comes to Android. One of these situations is why my initial attempt to try Android didn't turn out well with the Galaxy S. One situation as a developer I'm aware of I'm still probably bound by NDA, so won't raise here unless the EU investigation reveals it.

The EU has also mentioned they are investigating due to complaints from other US based businesses. This isn't an EU vs US situation.
