There is a certain convenience to common things being commonly available in common languages. It's just nice to be able to jump between languages and have a lot of things work the same way, or to be there at all. I suspect that lambdas have gained enough modern mind share with developers that it's just a nice thing to have. A lot of tasks these days probably have the look of "put lambda here" to a lot of people. Whether Sales Guy and Manager are playing chess over the matter, it's just nice to be able to write the code the way that you would naturally write it.
