Companies profiting off Open Source is a very common pattern. Look at AWS (amazon web services) long list of 'managed' services, and there are quite a few open-source candidates. I'm not saying Amazon is not adding anything to benefit users there, they are, but adding a management layer (with all their in-place templates/patterns for similar things) - wouldn't be a huge development or research effort - contrast that to developing the original code from scratch.

Then there will be engineers who will get certified on this tech, training companies, and the ecosystem just keeps taking root, where the source of the innovation is all but forgotten.

The owner of WPEngine is investing in billions - and they are contributing relatively little to the software that they never wrote, but got for free.
