But claiming "We love open source" is a blatant lie: the article makes it really clear that they only love the aspects of open source that are to their advantage. They should better honestly write this.
If one believes that open source something can lead to a loss of profits, then one must believe also that the open source software they have likely used has already made that sacrifice. It's easy to appreciate the sacrifice of others but then fail to make it oneself.
This metaphor is alright for this actually.
It could also just mean supporting projects financially, with developer time or filing issues.
Everybody loves benefiting from free software. Who wouldn't? But if you aren't willing to contribute, then it probably isn't worth mentioning. All you're saying is "We love getting free stuff".
