First of all you’ve swallowed the myth that Fedora users are beta testing for Enterprise software. That said discouraging people from voluntarily beta testing is bad for the community and fundamentally against the spirit of open source.
As a long-time Fedora user I think Red Hat’s backing is good for Fedora because it means they have a solid source of funding. Apart from the resources that gives them, that way they can be entirely user-centric and not be tempted to sell user data, run ads or anything else against the users’ interests.
There’s a lot of hearsay going on around Red Hat at the moment, some of it has grains of truth, some of it has been distorted beyond fact, I’m sorry that you’re a victim of it.
