I am speaking for myself now, and sharing my vision, Keymaster may have different opinion, and his word is always the major one:
Once Corona goes commercial i suppose there will be a Main website presentation with shop, gallery, and also appropriate mail channels for information and support, as well as forum independent bug reporting/feature request system. Of course when Corona goes commercial, it will not be sold via forum and support will not be primarily done through forum either. But that does not in any way interfere with forum continuing to exist in same way as now.
Those who do no like forum environment will never have to interact with forum in any way. They will be able to get support, request information or resolve licensing situations via email conversation, which i expect to always be handled in a respectful formal tone. Same will apply for bug reporting and feature requests. So if one does not want to visit forum, they will never have to, and it will not prevent them from using Corona in any way.
At the same time, i hope forum will continue existing in the same form, with exception of removing build distribution and bug reporting parts from it and replacing them with links to appropriate channels, but i do not see anything wrong about sharing official information on forum as well as interacting with users on friendly level.
I am sure most of you know how hard is to reach out to for example Autodesk, and let them know about things in their software that make you life hard, or that could be improved in an innovative manner. They only rarely contribute to their own forums, and if they do, it is usually only regarding to some disastrous mistake they have left to slip through into their software.
I think being able to engage in a constructive discussion directly with the developer(s) of the software is always good for both community and software itself. Especially when users know their input can actually change something, instead of being just time wasted writing down ideas no one will ever read, because marketing department of the corporation has already made up their mind based on a research on how to sell as many new seats as possible.
