Canonical is at a disadvantage here because Red Hat directly employs or has significant established relationships with many of the people who make kernel release decisions. Plus, RHEL is the de facto standard
enterprise distribution, which means any decision the kernel community makes regarding what they believe "enterprise" requires will often be a reflection of Red Hat's plans.
But what benefits Red Hat in the enterprise world is to their detriment in the consumer world. There's a reason the Debian/Ubuntu package ecosystem is richer and more featureful than RPM, and this is why Ubuntu dominates in the container space--because almost any piece of software that one could expect to have been packaged has been packaged as a .deb and already exists in the default package archives. I can't count the number of times I couldn't find an RPM--certainly not in the default repositories (RHEL, CentOS, or even Fedora), but not even in the third-party community repositories. And those that do exist are of lesser quality than the comparable .deb, for various reasons. (That is, the long-tail of packages is of higher quality for Debian.)
By pushing Snap, Canonical is definitely going astray. Ubuntu's competitive advantage is the Debian package ecosystem. Both Canonical and Red Hat seem to underestimate the role and importance of their respective packaging ecosystems. How many projects to revolutionize or replace RPM/Yum/whatever at Red Hat have crashed and burned? Many, though it's hard to count because half-way through they often realize what they're trying to do is functionally or even technically impossible (as with their aborted 2017 plans for RPM package streams), and scale things back to iterative improvements.
Containers are a security nightmare, and pretty much the only reason to pay Canonical and Red Hat licensing fees is for security and bug fix maintenance of their package archives. On our large Kubernetes clusters at work there are thousands of open CVEs for the containers that are being run, and we'll have to boil the oceans to get them all updated, let alone keep them updated. But updating packages is as simple as an apt-get/yum upgrade[1], and rarely do you have to worry about anything breaking, especially relative to the pain that updating containers regularly brings.
[1] If the container uses Ubuntu, Red Hat, etc you can sometimes just rebuild the container to get the newer packages. But that assumes you control the container image. Most containers come from third-party, decentralized sources (that's the point!). But Docker Hub doesn't cajole and coordinate container owners to update their crappy images. It's no substitute for the orchestration of people that are traditional package repositories.
