You may not feel this way, but think of downloading docker, as a non developer. You are probably following some tutorial, and really have no idea what you are actually doing. What if a container you are downloading is dangerous, or becomes dangerous. What if the version of the platform you have eventually becomes risky, due to a hack/0day? You are basically downloading an entire OS/execution environment, that makes it seamless to run an entire environment, while doing nothing. How would the company send an email/warn you etc, of some basic info that could really help you, or make your experience better? This isn’t som H&M mailing list to take your money. This is real, marketing aside, maybe they actually care?
