It's deceptively easy from the outside to say "do this, do that, and do the other, and TR will be saved." The problem is to add more content, or explore new platforms, you fundamentally need to hire more people to buy the time and attention needed to let those new ideas flourish. Otherwise you burn out your existing talent and lessen the quality of everything you're trying to do. Good people cost a lot of money, as you may well be aware if you're a person with a job yourself, and lots of good people cost an absolute crapton of money.
Money is in fact the lifeblood of any business, and drfish has already noted that there ain't much of it to go around in the written/longform PC hardware journalism space any more. Money also buys you time to pivot, and when you're short on money, you're also way short on time to formulate real, sustainable business plans, rather than throwing Hail Marys in the last seconds of the fourth quarter and seeing what gets caught. As drfish has already sort of said, the vicious cycle is that without money, media outlets can't hire people. Without people, the content river dries up, and readers leave. Without readership, selling ads becomes that much more difficult, and that assumes companies even want to buy ad space on your site to begin with when most people are blocking ads and directing their attention to YouTube and Twitch. With shrinking revenues, you can't retain staff, and on and on it goes until you can't stay afloat any more. Worse, this is like a chronic disease with progressive effects. You can't just spend some money, snap your fingers, and say "I have a successful and healthy website again."
It's seriously heartening to see the TR community asking how to help and throwing around ideas about taking up the testing mantle (you really are the best and brightest community on the 'net and I miss writing for you all). The unfortunate and sobering part is that people with lucrative day jobs and the wherewithal to donate large swaths of their spare time and the use of thousands of dollars (if not tens of thousands of dollars) of specialized equipment to the cause are exceedingly rare if not nonexistent. They are certainly not the foundation of a sustainable business, because they can't devote their full attention to the crazy, irregular and often long hours required to do this work. Remember that if you're trying to compete with established pros in this space, you have to have production values, too, and that's just to try and scrape out a foothold against numerous experienced people who have already been doing multimedia production for years and years. Cameras, lights, and AV gear all cost eye-popping amounts of money, not to mention set design and set dressing.
I don't mean to dampen the enthusiasm for community hardware testing, but I will testify from firsthand knowledge that even with the amount of automation we did behind the scenes, testing CPUs and graphics cards "the TR way" and writing the accompanying article(s) consumes well in excess of a 40-hour work week. It's not something you can do in your spare time if timeliness is the goal (and timeliness is important if you want access to manufacturer samples). Reviews are never as straightforward to plan as charting out something like "10 graphics cards, 10 games, three runs each and I'm done," either. Stuff breaks, you goof settings, data gets munched. Sometimes your test system betrays you and you have to retest everything.
This is easy for one person to do full time if you are single, have no kids, and have no life or responsibilities outside of a burning passion for hardware testing. It is not and cannot be a hobby if you care about producing trustworthy data that lets you cover products at the level TR readers have come to expect. I say all this only because it's probably one of many things that would have to change if readers started throwing together test systems and writing about it.
I don't know what the future of TR holds -- that's for others to chart at this point -- but it would really help if some gerbils would go out, win the lottery, and write some really big checks to start with.
