Sorry, you are slightly mistaken and mislead the colleagues present here.

The OpenIPC project is completely open wherever possible, but it allows the use of various streamers Divinus/Majestic/Mini/Venc/other and various binary drivers and libraries if the chip manufacturer does not provide open source code.

The Divinus streamer is a great alternative to Majestic and it is open and also part of the OpenIPC ecosystem - https://github.com/openipc/divinus
