No, that's would be their value proposition or what every company on earth have been doing since inception, filling a gap in the market.

You seem to be claiming that their mere existence in the ecosystem would be a contribution, even if they were closed source. They would be providing value and attracting users in a butterfly effect style. Sure, that help and have a positive impact but is it a contribution to an open source project and the ecosystem?

My model is fairly simple, you can't claim credit for something if you did it involuntarily or with a different intention or it happened as n-level side effect of what you are trying to do.
