> SQL Server and Oracle, two of the database products with the largest market share

Agree on the first point, but is 'market share' - a metric comparing commercial sales revenue which by definition excludes open source software, really that relevant when critiquing a tagline for a FOSS tool implicitly targeting FOSS databases at a time when FOSS dominates?

If this wasn't an MIT licensed project without a single hint of a commercial offering I'd get it, but come on.
