If I understand them correctly, @geography082@lemm.ee’s point is not that it is wrong to monetize FOSS, but rather that companies increasingly develop open source projects for some time, benefiting from unpaid work in the form of contributions and, perhaps most importantly, starving other projects from both such contributions and funding, only to cynically change the license once they establish a position in their respective ecosystem and lock in enough customers. The last significant instance that I remember is Redis’ case, but there seem to be ever more.
