Let's look at it the other way. Current free ERC coverage is simply bad and there is little reason for it to continue like that.

If you want better coverage you need more money from somewhere. They chose to get it from paid subscription. The long term thinking about that is subscription -> better coverage -> sell coverage to more customers/tv channels etc.

Where do you suggest the money should come from, especially if rally is a tiny sport?
Some big sponsors suddenly appearing out of the sky?

...or do you think that crap coverage for little funds (and for free) should stay?

-----------------------
Well the number of spectators at the rally is limited and will likely stay limited or even become more limited in the next few years (COVID, travel costs etc...). The number of "possible" online spectators is unlimited in comparison.
So for long term the sport needs to aim for online spectators.

The really big discussion is if it should aim for online "live" spectators or "watch cool vids later" spectators.
