User perspective here.
It is often unobvious on what terms developer does or does not offer support. Unless it is in your face with huge red letters - it is an effort to figure it out, meaning most people won't do that.
So it is wrong to assume that people asking for free support are automatically freetards. More like it is a mix of freetards and people who have no understanding of how things work.
So I suggest three steps:
- Templated response that explains clearly and in detail terms on which you provide support.
- If they start to beg - second response with this video
- If they are still at it - add them to ignore list.
PS Justin does seem like a cold person ;) but he does excellent job at making clear how things work with Hybrid and support. It may seem unfriendly but I will take him as cold as it gets if that makes him money and in turn gets me free Hybrid downloads
