AWS have recently invested in DevRel and open-source evangelist type employees (to be found on twitter much of the time). I assume they understand better than anybody that the dev and startup dollar is enormous and crucial to their future success. This type of thing - and their past willingness to leach off open-source - has to have a marketing and sales impact - at least at the 'startup' top of the funnel. Is it sufficient to push AWS to change direction? Would be good to see a RocksDB, Cassandra or the likes emerge from AWS.
