ISM is tragedy of the commons; make it free, let anyone do anything and it becomes junk. Carriers need something they have exclusive use of.
Carriers don't need 6GHz for backhaul. They have fiber and cable and (other) microwave. Not to mention the ability to shape their own links with antennas and beam forming and do a good job of it rather than a "default job." What they don't have -- and shouldn't be given under any circumstances -- is the excuse to build a moat in the bustling public park.
The devil is in the details
There are some formats, perhaps the one(s) the user wants, that do not require a JS runtime
Interesting that "signing up" for a website publishing public infomation and "logging in" may not always work in the user's favor. For example, here they claim it limits format availability
"Format availability without a JS runtime is expected to worsen as time goes on, and this will not be considered a "bug" but rather an inevitability for which there is no solution. It's also expected that, eventually, support for YouTube will not be possible at all without a JS runtime."
It is speculated that this format availability might change in the future
