Pretty sure they were referring to the amount of resources Valve puts in to keeping the PC platform open, including the vast amounts of ooen source software they create and the ones they contribute to, primarily for Linux. Hiring devs to work on FOSS, contracting out to FOSS companies like Collabora and Sourcehut, these are great things to do. Valve does plenty bad, like any big company, but one thing they don't do is use their marketshare monopoly with Steam to create an actual monopoly, lockin, etc. Even their hardware isn't locked down.
