Really? OK, lets use an example. There is a paid ($40 US) blog add-on in the RM that has effectively been abandoned by it's developer (whom otherwise has a good reputation). The developer has elsewhere (outside this add-on) said that he is no longer developing for XF until it's legal scenario has been resolved, and has not participated in discussion or bug reports for his blog add-on in some time. As we know, the legal issues were resolved a few weeks ago and despite being asked directly, the developer has failed to respond to provide any information on picking up development. In fact, he has been active in posting in the RM discussion for a competing add-on, seemingly encouraging development of an import from his blog add-on. The add-on is still available for purchase though.
This scenario is nothing something that XF, or its mods, feel is an issue? The 'pollution' of their official resources repository with add-ons that are defunct and unsupported.
