And commercial software may very well be one intern copying stack overflow to keep the lights on. Until the the day they stop and shutdown the product with no further updates. For example, the issue here isn't FOSS but rather a small corporate non-profit entity. The failure being the corporate governance, finance and management.

If anything, I think commercial is much riskier to have as a core dependency - they can unilaterally change the deal on you, and if they decide to stop supporting your use case, you’re completely SOL (I’ve had a couple of very close calls with this). With open source, you can keep it running yourself, because you have the source, and you always have the option to patch it.

How do you reconcile that with the fact that those company-backed projects you listed are themselves built on top of FOSS libraries?
