I’m gonna start off by saying I’m assuming the answer is gonna be because they want to push you towards the more expensive lenses. So they can make more money. And because they have a tight control on who is allow to make RF mount lenses, so they don’t need to offer as competitive value lenses. I just wanted to ask anyways, just because and in case there is any other reasons.
3rd party RF mount lenses (I know all the 3rd party RF lens, are RF-S mount APS-C as of this moment) and lenses for other mounts offer much more budget friendly low aperture and fixed aperture zoom lenses. So why don’t Canon offer more budget friendly low aperture and fixed aperture zoom lenses?

Over the years, I have found that budget friendly and quality don't meet anywhere on the spectrum. You get what you pay for.

Thank you for visiting and participating. I notice that you are making a generalized statement. Can you cite some example comparisons that you are making rather than generalizing. I have owned and shot the primary mirrorless competitors and found the same was true with their fast zoom lenses. Canon DOES offer some very low-cost fast RF primes. Marking a fixed aperture f/4 or f/2.8 zoom lens is just simply an expensive proposition. The quality and coatings on the glass, the number of elements, the electronics and motors and mechanicals are, from my view really a bargain for what we are getting.
Can you give an example of a third party lens that you feel is truly in the class of the fixed low aperture zooms for Canon (or any other manufacturer for that matter) that truly compare in image quality and support after the sale?
What lens would you realistically expect to see and at what price?

Canon does make them for the RF mount.
One common observation is how the Sony E Mount has a wide variety of third party lenses. I want to point out that those lenses were designed for the Sony bodies, which have dramatically slower frame rates, up to 12 fps, compared to the 30-40?fps in Canon bodies.

In a word, "Fulfilling specific buyer demands." When I did DSLR 101 classes by far, albeit a small local sample, had Rebels with the standard kit lens or lenses. The average person is completely happy with their Rebel.
As with virtually everything in life it is all about the money. Canon has the most extensive line of lenses of any company in the world and perhaps even several of the others combined. Then there is customer service and support. There too, Canon is at the top. It all costs and return is what keeps Canon profitable and in business.

@Waddizzle I would also like to further your point. Most E/ FE Mount lenses can only get the rated high FPS shooting with their own native lenses. 3rd Party lenses cannot achieve this and also certain video features aren’t available when using 3rd Party lenses. While it might seem like Sony has the most 3rd Party lenses. You can’t use your Sony E Mount camera to its fullest potential. Sony got a lot heat for this when their flagship A1/ A9 III bodies were released. That only native Sony E/ FE Mount lenses could achieve 30+ FPS in stills mode. But 3rd Party lenses were limited to 10-15 FPS. Forget about adapted Minolta/ Sony A Mount lenses. Those you’re lucky to get at max 8 FPS. Especially with older screw driven AF lenses. Motorized lenses could achieve 8 FPS. But the mechanical Aperture limits how fast you can shoot. Minolta/ Sony never adopted electronic Aperture control like Canon did. They were also late to adopt SSM. Which is Canon’s equivalent of Ring Type USM. Sony mainly brought motorized lenses to the A Mount. But these lenses SAM which is Canon’s equivalent of Micro Motor. So they were able to AF. But not all cameras can AF motorized lenses. When Minolta made the shift to in lens AF motors. They added 3 additional pins to the lens mount to allow this. But older cameras lacked these additional pins and then the additional cost. So most users stuck with screw drive lenses.
