Frankly it annoys me that there are no desktop distros that are maintained for longer than a year or two
Allow me to rid you of your annoyance:
Above you talked about 6-12 months, now it suddenly changed to 7 years...
Read a little more closely. Fedora releases stop being supported after 12 months, and new releases come out every 6 months. RHEL releases lose support after 7 years, with new releases every 3 years or so.
Do you seriously use that old disk images carried over to new HW, or do you perhaps re-install the OS from scratch to new HW a bit more often than that, after all?
This is exactly the point: the support cycle is long enough that I will generally have to reinstall at some point before the 7 years are up, and I can do so at my discretion, when I have time available. I do not buy a new machine every 6-12 months; were I to stick with Fedora, I would be reinstalling (or praying that the upgrade option will work) on the same hardware year after year, and then having to take a few days away from work to rewrite configuration files, find workarounds for deleted features (or worse yet, added "features"), get my machine to connect to the network, etc.
I'm glad to here Ubuntu LTS works for you and lets you get your work done. I'll be over in here RHEL land getting my work done, and I'll be ignoring Google and their efforts to get me to do something else.
Red Hat - or anybody else, for that matter - is free to take the pure open source Chromium and port it to RHEL
There is a reason Chromium has not made it into Fedora's repositories (and by extension, RHEL):
Basically, the problem is this: Chromium depends on extensions to libraries that have not been merged with the main releases of those libraries, and so having Chromium on Fedora would require either static linking (giant packages) or maintain separate sets of libraries just for Chromium. Neither of those options is something that Fedora will do, and if Fedora is unwilling to include a package in its repositories the package as almost no chance of being included in RHEL. Years have passed since the problem was first discussed with Google (see the link), and there has not really been much progress, mostly for the same reasons that RHEL6 is not supported by Chrome: Google does things their way and is not going to change that for someone else (regardless of that other person's reasoning).
Just "vote with your wallet".
Sounds like rich people get more of a vote than poor people.
The fact that thieves may (and do) steal legally held weapons is an argument for stricter gun control.
Indeed, but the key thing to recognize here is that the kind of guns that thieves steal are handguns, not rifles. Unfortunately, people keep talking about "military grade" rifles (which is a deliberately deceptive term to use) and the urgent need to keep those kinds of guns out of the hands of lunatics, while ignoring the fact that most gun murders involve low-caliber handguns. I am glad people are talking about gun control; now we just need them to stop making idiotic statements like, "We're not talking about taking away anyone's right to defend their homes with a handgun, we just want to restrict access to military rifles!"
A conclusion is simply the place where someone got tired of thinking.
