Couple of points: 1. It always struck me as surprising manufacturers would allow others to reverse engineer their products and become competitors. 2. Users have a myriad of choices both new and used from Canon and other manufacturers in the EF mount that work flawlessly on mirrorless via an adapter. For those who need or want to save money on glass, this is the way to go. 3. I have read (but can't confirm) that Canon is restricting others until they get their own catalog filled out. They don't want others getting products out ahead of them. They do allow manufacturers who make specialty products, like Lensbaby, to produce R mount lenses.

It has been widely discussed and Canon has issued statements, they are saying cease to all third=party makers who had made a few RF lenses and/or ready to release new RF lenses. Those makers have pulled those RF lenses and Canon is saying no more will be allowed in the market.
On the opposite side of this philosophy Nikon is now even opening up its Z-mount to Tamron and other third party makers and is even badging some Tamron mirrorless lenses as Z-mount.
Sony has had an open E-mount for a long time, and there are over 200 quality Third-party lenses in E-mount from Sony, Sigma, Tamron, Samyang/Rokinon, Zeiss, Yonguo, Viltrox, Tokina, and others. The E-mount is the most widely produced and used mirrorless lens mount in the world. With additional quality E-mount lenses being introduced all the time. That is part of the reason Sony leads in Worldwide Mirrorless camera sales. Check the CIPA numbers if you doubt that. Sony and now Nikon have decided it is better to allow more people with all budgets to be able to afford to fully embrace their mirrorless systems.
IMHO, as a longtime pro that has owned and shot with the best of Nikon, Canon, Sony, Leica in my 48+ years in the business, Canon is a big, and often arrogant maker that has lost sight of building up its base. Even Leica shares the mirrorless L-mount with Panasonic and Sigma (yes Sigma makes mirrorless cameras), using L-mount lenses from Leica, Panasonic, Sigma and other third-party makers.
Full disclosure, Tamron is partly owned by Sony.
https://en.wikipedia.org/wiki/List_of_Sony_E-mount_lenseshttps://en.wikipedia.org/wiki/List_of_third-party_Sony_E-mount_lensesAs most photographers and industry experts worldwide agree, Canon is eventually hurting themselves in the marketplace just to keep a monopoly on RF lens sales, and Nikon and Sony will reap the benefits as it is a fact that many are now moving away from the R series and moving to Nikon Z-mount and Sony E-mount bodies where they will have a greater choice of quality E-mount lenses in all price ranges. It does matter to many around the world.
The still fairly limited RF lens series choices from Canon are either cheap kit lenses, or very expensive top quality RF lenses. Canon's RF lens lineup is still slow to fill out, and is nowhere as extensive as its mirrorless competitors, just the facts. Not everyone is willing to wait on Canon to slowly fill out its top RF lens lineup, and be forced to pay high prices for top quality Canon-only RF lens, if and when they are available. People have photos to make now, not later.
The top News Services around the world have moved to Sony and Nikon fullframe mirrorless for all their staff photographers and staff videographers, worldwide. They aren't waiting for Canon to fill out their RF Lens lineup either.
