I think the motivation is important. Many FOSS projects are sharing something the author considers useful to the world, as a way of making it better in a way that they know how. Its a lovely gift and I'm happy to know about it.

Others are there to promote lock in to some cloud service, or increase the authors rep as a 10x hacker and those are skeevy because the author is skeevy and did not have joy in their hearts.

All corporate ads ate the second kind.
