Disclosure: I am the author of that post and Product Manager for this project as well as other related work like Certificate Transparency and Key Transparency. While I can not say what Google will do in the future, I can say we are very supportive of Let's Encrypt. We have provided them funding and I personally act as an advisor to Let's Encrypt. In short, we love what Let's Encrypt is doing.
