I can't say I'm a big fan of using RHEL personally but at work I've usually stuck with them on big servers just cause it's less driver/support hassel and it's easier to find people who can administer them.
I generally can't afford RHEL, though I've deployed it in the past for clients who wanted a commercially supported distro, but I get most of the benefits of RHEL by running Scientific Linux or CentOS on my servers. And I run Fedora on my laptop, which is still my favorite desktop distro, by far (I keep trying Ubuntu, every couple of revisions, and finding way too many things to hate about it).
Anyway, I think Red Hat's success is a great thing, particularly for companies trying to make a living in the Open Source world (which mine happens to be).
I used to work for Novell/SUSE and even we didn't hate Red Hat. So I can't imagine who, in the Linux community, is hating Red Hat.
It tends to be sour grapes about Red Hat and derivatives being the most popular. That may change now that Ubuntu is approaching similar popularity on servers (which is the sort of Linux users I interact with). But, I also hear quite a bit of bellyaching about RPM and yum, which I can't fathom...I prefer them to apt-get/dpkg, though both are perfectly acceptable and I rarely complain about either.
But, I hear a lot of complaints about just about everything. So, maybe Red Hat just gets the biggest share because they get the biggest share of the money in the Linux distro market.
Confusingly "oVirt" has in the past referred to some different software. That's what you get for recycling a convenient domain name that we happened to own ...
