I don't think anyone knows, ffupdater reports 'it is no longer maintained'. Csagan5 was awesome, they didn't get into politics, they just made the best Chromium browser for Android. I hope they are OK. I hope they come back.
One of the contributors is keeping the project alive here but it is not exactly the same.
For a Firefox fork (my main browser), there is the excellent Mull from DivestOS
Yeah I switched to fennec for now - mull's too hardened for how I want my browser to behave. Someone did point out mulch, from the divestOS project, to me recently in case anyone is looking for a FOSS chromium fork that's still maintained. I installed it through FDroid on stock android rom with no issues
She's dead, sis. Try Mulch if you specifically want a chromium-based browser. I use it as a backup for sites which don't work correctly under Firefox. You can add the divestos repo to your Fdroid client for auto updates.
No clue, the dev said in one of the issues on github that "nobody stopped developing the project" or something similar, yet there's no sign of the project being maintained.
Luckily one of the core contributor of the project has a fork, which is actively maintained, so you can use that: https://github.com/uazo/bromite-buildtools
It does not have the bromite branding, but it contains all the bells and whistles.
Eventually it is going to have its own branding and probably will be called Cromite if I remember correctly.
