I realised there is something worth protecting even more that just my software's copyright. The community backing it!
I wrote a blog post about it here: https://www.jedimark.net/node/5
The GPL sucks a little, but SleepyHead stays GPL, because screw the abusers, SleepyHead is awesome because of the community behind it, and none of us will stand for that crap!
SleepyHead will move to a "pay zero, or more if you want" software business model, rather than just "donations are encouraged" to help me cover costs... not really much of a change, but I will try to make things a little clearer regarding the amount of time and money to that goes into producing and maintaining SleepyHead.
I would like to take this opportunity to say a big thank you to all who have supported SleepyHead project in this regard, it has been hugely appreciated!
And I want thank you to all of you, for helping me regain balance over this stuff.
