I don't see anyone investing money into something with no hope for a return. That's why you're asking for.
It is done all the time in the computer and internet technology worlds. All the standards the internet operates on, as defined and laid out in RFCs, are examples (
here,
here). Free and open source software, and even closed source freeware, which have been things since the dawn of personal microcomputers, are examples of giving away money as a matter of good will. Remember: not investing the time you're devoting to making such wares into other, paying forms of employment is the same as investing money into those things themselves.
And the open and closed source freeware products available these days are not tinker toys. You can technically run a fully-functional, fully-featured computer in a fully productive fashion without paying anything for any of its software -- from the operating system up -- thanks to the open source community. Only the hardware will cost you, and since computers exist in a technology cycle where they're tossed for recycling on average after just a handful of years, often times, that hardware can be free or nearly free for you, if you're not interested in bleeding edge processing loads like BTC mining.
I think when it comes to public technologies like broadcasting, the standards that underpin their inner workings (modulation schemes, codecs, etc.) should only be considered for acceptance by the FCC if no patents are attached. Make all your money selling the hardware and competing to offer the most premium software implementations. Otherwise adoption rates falter, because companies always drag their feet on implementing patent-encumbered ($$$) technologies. Sometimes you even get chicken and egg infinite loops where nobody wants to pay for the rights until there's a large enough market demand, but large market demands fail to materialize because everyone's hesitating, keeping the technology in a state of obscurity. And then you have the dreaded scenario where multiple parties offer competing specifications and begin suing and counter-suing. Whole technologies can sometimes come and then go obsolete during those lengthy legal battles. Unsubtitled hint:
At one time, FM was a proprietary technology. Radio companies had to pay to use it. Then the patent ran out. HD is still under patent. Any new technology would also still be under patent laws.
Were they ever
able to pay to use it to any meaningful degree, with all the obstruction Armstrong endured for years after his invention of it? I always thought FM was an example of a technology that was able to experience rapid adoption because its patents had expired by the time that adoption finally occurred.
