While the corporate momentum switched to Apache/MIT licenses, there are strong communities built on AGPLv3/GPLv3.
* Nextcloud - file hosting (AGPLv3)
* Source Hut - git hosting (AGPLv3)
* StreetComplete - OpenStreetMap editing (GPLv3)
* F-Droid - Free Software "app store" for android (GPLv3)
* NewPipe - alternative Youtube frontend (GPLv3)
While these aren't necessarily used by large corporations, their individual communities are thriving and strong.
The shift toward SSPL and Commons Clause licensing is another argument in favor of AGPLv3 licensing. Amazon/Google often won't touch your AGPLv3 code (and you can still sell proprietary licenses to other companies that can't/won't use AGPLv3).
