That's not what "Canon" said. I can understand your confusion because the actual statement was grossly misrepresented by a number of websites seeking to score more hits. But here is what was actually said:
“As you know, last year we launched the RF mount and EOS R system," said Richard Shepherd, pro product marketing senior manager at Canon Europe. "To date we’ve launched ten critically acclaimed lenses, and as it’s a new system we plan to continue this, launching more RF lenses while still fully supporting the EF lens system. And of course, should the market demand it, we are ready to create new EF lenses. But for now, our focus is on RF.”
So all of this nonsense about Canon abandoning the EF mount can be traced to one Canon Europe employee who simply said they were concentrating on RF for the time being.
Given the extensive EF system, it's no surprise they are comfortable pausing new lens development while they build out the RF system.
