Identities are somewhat decentrallized, but it's pretty different from ActivityPub. People can host user data separately, but it isn't really an instance. It is technically possible to have other relays (basically instances), but requires handling all the data on bluesky to connect to it. It would cost probably 50-100k USD/year, and that number will go up as more people join or if there's more relays.

The github page for overleaf seems to indicate the community edition is AGPL.

I would try [email protected]. There used to be [email protected] but it looks like that site died.

Google is still appealing it, so at best that will happen next year. But yeah, they're probably adjusting their budget in anticipation.

Mozilla is set up as a non-profit with a for profit company as a subsidiary. The corporate Mozilla handles working on Firefox, mostly using money from Google for setting it as the default search engine. Because of that separation I don't think they can easily mix those two piles of money together.

There's this section from their FAQ:

Don’t Mozilla products, like Firefox, earn income?

Firefox is maintained by the Mozilla Corporation, a wholly-owned subsidiary of the Mozilla Foundation. While Firefox does produce revenue — chiefly through search partnerships — this earned income is largely reinvested back into the Corporation. The Mozilla Foundation’s education and advocacy efforts, which span several continents and reach millions of people, are supported by philanthropic donations.

There's Mines3D on android, although the graphics are still 2d and it's a pain to play.

Some other fediverse software like hubzilla and sharkey let you migrate posts, so I wouldn't say it'll never happen. I don't think anyone is working on it though, so probably not anytime soon.

I feel like it's really far from being open. Besides the training data not being open, the more popular ones like llama and stable diffusion have these weird source available licenses with anti-competitive clauses, user count limits, or arbitrary morality clauses.

They probably argue that rescuing or even interacting with sick animals can spread disease and is therefore bioterrorism. If you stretch the definition enough almost anything can count.

No. It's got a "source available" license allowing only non-commercial use, and revokes the license for anyone who tries to sue them.

I think they switched to usually using bing results last year. Their support site mentions they use both backends. I'd guess which one you get depends on which API is cheaper for each country.

I think that's still closed, just poorly done in a way that isn't very accessible.
