Elasticsearch is relicensed again - this time adding open source copyleft license AGPL

Elastic's title got me so excited.
Then I read the fine print.
No, Elasticsearch isn't going back to the original Apache2 license.
Instead it's adding AGPL copyleft license (on top of the non-FOSS ones).
What are your thoughts of the move?
