My thought for shorter trials: If something more important derailed the trial then the product isn’t solving a problem with enough urgency for you and you were unlikely to convert.
Moby is the fedora like oss project and docker is the RHEL like commercial product. Purely a clever rebranding job. Timing is perfect - now that enterprise is adopting the technology, when you tell your boss you adopted moby he/she will say- but the CTO wants to be seen as being innovative for adopting this new technology and ita called docker not moby!
