It's annoying, but it's pretty standard in commercial databases: if your competitors refuse to allow public benchmarks, all it can do is hurt you.

How standard is it? As far as I know among databases MS SQL and Oracle do this but do other commercial databases do this as well?

It’s common enough to have a name: “DeWitt clause”. It sounds like IBM is the only major commercial rdbms vendor to allow benchmarks?

That article only lists MS and Oracle though. Apart from IBM, I don't think CockroachDB Enterprise has such a prohibition, nor does Google Spanner (I think?), nor does Amazon Aurora (again I think?). And of course all the open source competitors don't have this clause.

Basically my impression is that DeWitt clauses are common enough to be well-known, but still in the distinct minority. That's just an impression though.
