"this will just encourage the further replacement of American citizens with H-1B's from India who will do whatever upper management demands, because they have no choice.

That said, I don't think the reasonable conclusion to come to when someone is supportive of a product is that they are invested in it. Sure, suspicion is a healthy thing, but for the record you can look through my comment history and see I recommend LeetCode and a coding book called EPI. No compromising connections—I just like the products and let people know about them when I see people talking about the topics. ¯\_(ツ)_/¯
