It doesn’t have traffic data, which is probably the biggest disadvantage. The maps are user contributed, so the quality varies widely. Depending on where you are, it’ll be ridiculously detailed with individual bushes in a park, or it’s incorrect or outdated and you can’t find your destination. I usually use this or OSMand, but I still keep google maps on another profile as a backup.

I don’t think there’s one that supports all of them yet. Probably the one that can handle the most is fedilab, which can handle mastodon and friendica, as well as a bunch of others like pixelfed, peertube, and pleroma. There’s also raccoon, which has separate apps for lemmy and friendica.

It was pretty heavily associated with the alt right a decade ago as it was getting more popular. Some alt right meme communities like frenworld and clown world were centered around it, with overtly fascist pepe variants. It’s gotten more popular in a lot of other circles, but if someone identifies enough with it to use as a profile picture I’d at least check their posting history.

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.

I think they just have multiple test instances to test federation between them.

None of the options are that great right now. I still mostly use Jerboa, and go to the PWA for things that don’t work. Other android apps you can check out are thunder that has an alpha out, memmy which only has an iOS beta so far, but plans to be cross-platform, and lemmur which is outdated and is incompatible with current lemmy, although there’s a fork with more recent development so it could possibly come back at some point.
