Mastodon gGmbH is a non-profit (only since 2021), but that is not what makes it ”not possible to buy”. The software is licensed under the GNU Affero General Public License v3.0 so any code based on it, or any modifications, have to be made freely available.
I guess a big player can come in and make a big instance and lure people there (easier-to-use, better performance, apps, etc) but they would have to surrender and make available any code changes for free.
Now a billionaire could just refuse and drag things out in court. But Mastodon as we see it would still be open source and free and possible to install for anyone. The community would likely rally to best any improvements.
So there is no way a billionaire can take away the premise of open-source software and our option to use Mastodon for free. But they could use all sorts of tactics to make something else appear more attractive. Some may be seduced.
I’ve not stayed updated on what is happening with Trump’s TRUTH Social, for example. Which is a Mastodon instance.
The fact that it is, however, doesn’t matter to our use of the software. And we don’t even have to be affected by it.
