My opinion: Good. Those plugins shouldn't have been in the repo anyway.
Additional: I want to clarify that I'm not saying that the guy is a spammer and I really don't give a crap about his marketing newsletter and such. The reason I don't like his plugins is that they have a forced registration and/or activation when all the functionality is in the plugin.
Consider Akismet and
WP.com stats. These have a sort of forced activation in that you need an API key to use them. However, the actual main functionality of the plugin is a separate service. The plugin is really just an interface to that service, and the key is needed to access the service. This I have no problem with, as many services require keys.
These plugins, on the other hand, access no separate services as far as I know. The functionality is in the plugin itself, and yet there's a phone home and a forced activation methodology built into them. That code is totally unnecessary for the plugin to actually function, and that's my main problem with the plugin.
The WordPress Extend repository is
NOT an appropriate place for marketers to place their spam and lead-generation mechanisms, even if they attach it to actual useful functionality. It's one thing to make a separate service and require information to maintain a connection to that service, it's wholly another to require information for no reason other than to satisfy your own marketing needs.
