While this resonates with me and probably the majority of the HN readership, I also want to be paid (handsomely) to build things. But in every case where someone pays me to build things, they want to sell it to someone (if they haven’t already sold it before I built it).

I think the important difference is whether you believe the thing you’re building is good for the people that are buying it. Never have I ever seen vendor lock-in become a net benefit for those who have found themselves in its grasp.
