So how are people going to know who you are and how to support you? First time I'm hearing from you. Leave a note somewhere. Your altruism is appreciated, but you do need to eat too! Don't passively let capitalism take advantage of you. You don't need to extend your values to corporate.
Money still runs the world. Windows or FOSS devs. I wish things were different, but you are wasting your political support on something that is not a big deal.
Ubuntu Pro is hardly an ad and not comparable to candy crush. Letting people know of a service to get more support is within scope (which is a target for enterprise anyway). To be clear there are better things to criticize about Canonical.
