Ask HN: As an app developer, do you care if an SDK is open source?

When integrating a third-party SDK, via Cocoapods/Carthage/Gradle/etc., do you look up the SDK to determine if it is open source before using it?

Does your company have strict requirements around this type of thing?

Does the decision change if it's for iOS vs. Android?

In short, if you were to build a new SDK today, how hard would you fight to make the SDK open source from day 1?
