I remember this post as the day that Keras died. Very strange political powerplay on the part of fchollet, and did immeasurable damage to the community and code that used TF, not just in that PR but also in the precedent it set for other stuff. People legitimately were upset by the attempt to move tensorflow under an unnecessary Keras namespace, and he locked the PR and said that Reddit was brigading it (despite it being pretty consistently disliked as a change, among other changes). People tried to reason with him in the PR thread, but to no avail, the Keras name had to live on, whether or not TF died with it (and it very well did, unfortunately). There were other things working against TF but this one seemed to be the final nail in the coffin, from what I can tell.
I ended up minimizing engagement with the work he's done since as a result.
