In the case of Eclipse, I think you're missing that IBM is already the dominant contributor, and that indeed the project originated from them. So I doubt anyone is going to accuse Google of trying to purchase influence. But, it's an open source project, people and companies are free to contribute as much as they like or not at all. I don't use Eclipse regularly at the moment, but I have in the past and so I'm grateful to everyone who has supported it. I'm especially grateful for this particular donation, because one of the reasons I don't like to use Eclipse is its sluggishness (although anecdotally I do think it has gotten faster and more stable in recent years, and it doesn't seem any worse than Visual Studio in this regard).
