As for the CFP, one problem I saw when submitting a talk for Falco is that the concept "end-user" is very tightly scoped. I submitted a joint talk with a Falco end-user (Yammer/Microsoft). In the CFP when it came to select if this talk was from a "end-user" I was given a list of companies that appeared to be pulled from here: https://www.cncf.io/people/end-user-community/. Not all "end-users" are going to be part of that list, and we are most likely eliminating "end-users" because their parent company is not on that list (something which is probably out of the individual contributors hands).

Is your organization an end user? End user organizations do not offer cloud native services to their customers. End users generally do not have a commercial product on the Cloud Native Landscape <https://landscape.cncf.io/format=landscape> (though they may have created an open source project to share their internal technology). For more information, please see the kind of companies in CNCF's End User Community <https://www.cncf.io/people/end-user-community/>.
