My expectation is that Fedora community members who want access to particular data for some particular purpose should be able to request access. But that is something we’ll need to discuss (this thread is a good place) and figure out.
The timing is mostly a coincidence; I wrote most of this change proposal in August 2021, and it just took a very long time before I felt ready to propose it. At the time we were hoping that having telemetry would make it easier to justify increased investment in Fedora. Unfortunately, with the way things have been going, that seems unlikely now.

I have a slightly different goal: Fedora Workstation should be the premier Linux workstation operating system, period. 
That position is undisputedly held by Ubuntu currently.
That was the goal of the “What data might we collect?” section (above), which describes various metrics that I’ve seen requested thus far. I fully expect we would wind up collecting much more than this, but what exactly we collect would be up to the Fedora community to determine. My expectation is that Fedora packagers and other community members will have lots of use cases for data collection that I don’t know about yet.
It’s very common for developers to ask “how many of our users are doing X, Y, or Z?” and then complain that we don’t know. E.g. earlier today a user was requesting feed reader integration in Epiphany. I wanted to know how many users have a feed reader installed (because otherwise, it would be useless). A couple weeks ago, GNOME wanted to drop support for systems that don’t support SSE4 instructions (for GNOME OS and the GNOME Flatpak runtimes); we asked Endless to show us CPU data, and learned that a significant amount of their users would be unable to run Flatpaks, and so dropped that plan.
For avoidance of doubt, I don’t have any secret plan for what additional data to collect beyond what’s already mentioned in the change proposal. But I’m sure others at Red Hat and also Fedora developers who do not work for Red Hat do have some ideas. This thread would be a good place to informally propose particular metrics that you might want to collect.
What’s really important to me is that however we wind up deciding what data to collect, it should be done publicly via some sort of Fedora community process, and not wind up with Red Hat making these decisions in secret on its own. This thread is also a good place for proposals on how exactly that would look. In this change proposal I wound up proposing that FESCo would approve metrics, but there are many other ways we could do it.
Edit: This post originally said “SSE3” but it was really SSE4.
