Stefano Zacchiroli@zimoun @ArneBab it seems to me you are conflating the freedom of modification, which is in generally considered as something valuable for *downstream* in FOSS, with the fact that *upstream* author of a software can decide to change it in backward compatible or incompatible ways. The latter is true for any software, no matter its license, and I don't think that being FOSS has any impact on it.
