Hi @asdfadfadsfadsf, so sorry that this is frustrating for you. We require registration for downloading so that we can contact you about your specific download if the need arises.
That is totally @#$!#@$ argument, do you even believe this yourself? This not standard for any major distribution. I don't need this for system administration, don't need this for wordpress etc etc. Start talking with your managers to change this policy.
Actually your policy is causing for people not to be able to update on time.
Once registered, you'll get emails regarding new security patches - some you'll definitely need to fix vulnerabilities that come up for the install. I find it helpful - I don't get very many communications from Magento honestly. VERY few - and they're worth it. But I guess I get it.
