Con Sometimes hard to know which package to install from community package repository
The community repository contains multiple packages with similar names, making it hard to know which one to install. This is of course only related to using Chocolatey with the community repository, and you can look up the number of downloads to see which are the most widely used.
Con Some package installs aren't good or polished or don't install well
Macrium downloads the online installer, 7-zip doesn't associate files, PotPlayer is outdated, etc.
Con Uploading packages can be time consuming
It can take weeks to have a package accepted and with a fair amount of resubmitting for the dev/ maintainer.
Con Incomplete and conflicting package options
Not enough maintenance done to package library so there are different similarly-named or -versioned packages available, some broken and some not.
