It's somewhat scary the breadth that AWS has in their ecosystem now; however, Bitbucket is wrought with issues like:
- no large file collapsing, i.e. lock files
- random downtimes ( I wonder if they actually meet their SLA )
- feature requests on boards where Atlassian members ask why x is needed, followed by a slew of +1's, to only see someone ask 3 years later, "where is this at?"
I'm a jaded Atlassian user who believes they buy competition and then stagnant the product's evolution.
