I agree that it hurts them tremendously. One one hand, sucking the life out of the web ecosystem and then killing their vampire implementation is really bad.

I agree that it hurts them tremendously. One one hand, sucking the life out of the web ecosystem and then killing their vampire implementation is really bad. On the other hand, the alternative to shipping a DOOMED implementation is Google not shipping these in the first place, which people also don't want. The least the company could do to not destroy the ecosystem would be to open source or at least write up these implementations for someone to rebuild black-box. Realistically, any developer could write a blog with black-box reimplementations. An alternative is to keep a team explicitly for life support of these projects.
