Canon (and Nikon) didn't really change.
They played the same game during the EF era. I think many of us can remember the days when third-party lenses failed whenever Canon released a new (D)SLR. It took the third-party gang more than a decade to stabilize their compatibility.
I suppose one of the reasons for the (likely) late entry of the third-party players is that they were once bitten hard once, so they are taking their time now.
What I don't quite understand is that the R-mount cameras are supposedly capable of processing the EF-mount protocol. This may not be ideal in terms of AF speed, but why should this violate any patent? I could understand that a hacked R-mount protocol may violate patents but EF?
I suppose that Canon also used the EF protocol for EF-M? And Sigma released some lenses for EF-M.
Anyway, we are in the 5th R-mount year now. So 5 more years to go until the patents will be history.
