The web is full of SQL 2005 benchmarks, your claims they are somehow prohibited seem terribly thin. Plus you're still confused thinking you have rights by birth to something you don't actually own.
You are in denial. Read the SQL Server 2005 EULA. It's located in "C:\Program Files\Microsoft SQL Server\90\EULA" on a standard installation. This has been part of the SQL Server EULA for several versions now.
Any benchmarks you see were allowed by MS. The benchmarks you don't see weren't allowed by MS. Such was the case with Network World's benchmarking of SQL Server 7 on Windows 2000. MS didn't like the results, even though MS worked with them to tweak it for good results, so they invoked the no-publish clause in the EULA.
Network Associates has a similar clause in some of its software. They were smacked down by a New York judge after trying to enforce it by quashing a negative review. But then not everybody has the funds or a state AG behind them to defend themselves against unenforceable EULAs.

Exactly what specific rights do you claim I erroneously say I have? Freedom of speech?
