> Finally, it's amazing to me as a programmer how commercial minded designers are in tech. It would never occur to me to create a programming library where you have the 'basic' open source version and the 'optimized' commercial version.

Open-core (open source with enhanced commercial version or commercial first-party add-ons) model is not uncommon in software (libraries, applications, etc.)

Neither is having a downstream commercial derivative vendor being a major contributor of work and resources to an open source project, which is essentially the same thing. (e.g., EnterpriseDB & Postgres.)

It's not something that the design industry does but software doesn't.
