Buying a season ticket gives you admission to the ground or a live stream. Everyone got streams automatically every game last year because noone could get into the ground. This year we have an allowed attendance higher than our ST holders. Therefore everyone can attend. The club is assuming that everyone can make the game in the exact same way they have for years. They don't phone us to check if we're coming for an all-ticket game - they assume we are and sell a number of tickets relative to what is available.
The government advice is that people with Covid-19 should isolate and stay away from the general populace so the club have to put something into place to accommodate these supporters. If you previously couldn't make a game because of an anniversary/birthday/work commitments etc you didn't get a credit back on your season ticket. I'm not saying that it is right or wrong, it's an interesting one to think about. Is there any sport that gives you a video feed if you can't make the physical event?
I'm interpreting it in the following: as a season ticket holder I am invited to attend the matches unless otherwise specified. Given they have stated earlier this week that all season ticket holders who have purchased can attend, then they are assuming all 1,900(per last club update) will be attending on Saturday. If you can't make it, then it is up to the supporter to tell the club whereupon live stream access will be faciliated - they have given instructions on how to do this. We all know that the staff numbers at the club are low so contacting every season ticket holder individually is impractical but also fraught with disaster. Human error may mean that the wrong season card is de-activated accidentally meaning a supporter who turns up to get in has issues - particularly as i imagine we'll have supporters with duplicate names ie about 10 john smiths for example.
Giving everyone access to the stream automatically and with an activated season card is essentially like giving out 2,000 comps and open to abuse.
