The plugin directory is great, but many plugins are controlled by a single dev or company, and often end up going a direction of a premium or pro version, sometimes even removing functionality that used to be in a plugin and pushing it into the pro version. This can also create an incentive to put something into a SaaS service that is easily done in a more distributed fashion locally to the site. Even accepting donations can create some weird incentives for how to divide those among a number of contributors.
