I'd love to be corrected here, but my understanding is that the enterprise support and pro features model can be a pretty good business.

Big deployments generally need really good support and help to overcome scaling challenges. Who better than the library maintainers to offer that, and your customers have deep pockets.

Then on top of that, you run a business which basically creates proprietary Pro and Enterprise versions of a product which has tooling to operate the project at scale or in high uptime environments.

Then you offer your own cloud versions of the product as well (which I think Redis has been doing).

But in none of these cases are you creating a disincentive for anybody to use/adopt your product. You're simply creating value around the pain points.
