If you're truly worried about federating with Meta, you should probably also avoid all the other products they have their fingers in.
This includes all their web properties:
- Onavo
- Oculus VR
- Beat Games
- Kustomer
- Lofelt
But this also includes many web technologies that are ubiquitous around the web. Meta has either created or contributes code and resources to:
- React.js
- MySql
- Memcached
- HHVM
- Cassandra
- Scribe
- Hadoop
- Hive
- Apache Thrift
- Varnish
I suspect you'll have a hard time finding any website on earth that doesn't use at least one of these technologies.
