This is why it is good to build on the top of open source solutions
Does that really help? Even when open-source, it's only a matter of time before an Oracle or Google or Microsoft or Meta takes it over (if they didn't develop it to begin with). I wonder if it's less about the source code here but about the people involved, and how to prevent a consolidation of capital and power in the hands of greedy financiers. Maybe developing the projects as nonprofits (like Blender or Mozilla),…
Of course it can help. For example, when Oracle bought MySQL, it was forked and we got Maria. When Emby pissed off people, it was forked and we got Jellyfin. There are plenty of other examples.
Whether or not you like these products, the point is that open source gives the community the ability to continue development if the original project gets bought and/or otherwise changes its philosophy for the worse.
