I think the "issues" they are talking about are not necessarily the ones that ops people are meant to solve, but about the issue of ops acting as "gatekeepers" that often create perceived friction in the deployment(and even development) process. By Docker putting the power of what prerequisites are made available to individual applications running on servers, it bypasses the middle-man and gets the job done faster. That's not to say there aren't trade-offs when using Docker with ops as a service, but some (usually developers) would say the trade is worth it. Let's just hope they are writing their Dockerfiles with security in mind. :)
