@lxo I had assumed that, since the 3rd party distributor has not changed the software, it's the same version that mastodon released. So, if I wanted to exercise my four freedoms, I can always get Mastodon's source code, and change it according to my needs.
But if the 3rd party distributor can easily change it, and I can't, then it's a problem since I'll never get that modified copy of the source code.
