It’s good to learn about some cultural differences, for both me and you. In Poland, Santa is believed to bring the naughty kids bundles of rods (as in, leafless twigs). We call that “rózga”, even though the same word can just refer to a single rod as well.
I do not understand why would a developer (or development team) change the licensing terms of their software for something stricter, like Redis did. Could someone tell me what the factors are?
