This too. It's pretty important we focus on building a viable business (see current funding environment). Contrary to popular belief, building open source isn't free and takes time away from that effort. You have to make sure your stuff runs on the various platforms, you gotta triage issues...etc.

Now for certain products, such as databases, not being open is borderline a non-starter. But for many other infra categories, the customer doesn't purchase your product based on whether it is open source or not. For example, no one cares that Stripe, Twilio, or Plaid aren't fully open source. Customers just want the API to work.

Personally, I'd like to see Seam go more open as we get more resources/bandwidth. We've already published a few things (https://github.com/seamapi) and I'd like to do more over time such as publishing firmware, open connectors, backends you can run anywhere...etc.
