Of course not, their individual contributors formed business models that make sense, and work at those companies instead. Companies that are, I must again reiterate, linked directly from the official PostgreSQL.org website, in case there's any confusion on pedigree.
"Our consultants are recognizable from their many contributions to PostgreSQL"
"Our co-founders have written several books ... [co-founder] is also a core developer and project steering committee member on PostGIS and pgRouting projects"
"With a strong focus on PostgreSQL, they recently launched Percona Distribution for PostgreSQL, which delivers a single source, enterprise-grade, open-source installation of PostgreSQL Core Distribution." (Custom sales on software products based on the open-source original? Sounds almost like what AWS did with Redis)
Obviously these companies are likely to give back monetarily to the things needed by the open-source team, if only because their viability of their own business relies on having the open source product to sell expertise around. But a lot of companies simply use PostgreSQL and pay nothing, and that's fine too. It's all part of what it means to be an open-source product.
There's ultimately no reason Redis Labs couldn't have been successful as the Percona or KDAB of their own product's ecosystem. I guess they figured there was more money in hosting than services, or maybe Redis was simply too foolproof to need consultants?
