Surprised no, upset yes. The game has worked damn hard in uk, where it faces enormous challenges, to get govt and corporate support for this tournament and to be spat on by the arlc is a disgrace. Especially given the only reason was their concern about having to delay the start of nrl by a couple of weeks.
If you want to see growth of the international game and get it back to where it was in the 90’s the last thing it needs is it’s credibility constantly undermined by the strongest nation. Imagine the backlash in union of the all blacks behaved like the arlc does.
Here's the problem you, and apparently a lot of other people, don't want to face; the NRL and clubs have significantly more to lose both financially and in competition with their local competitors from delaying the NRL a couple of weeks and risking a covid outbreak in their playing group, than they have to gain from participating in the WC. It really is that simple, and sooking about it isn't going to change it.
Also the idea that the NRL are the ones that constantly undermine international footy is just short-sighted BS. The only reason that international RL still holds any relevance at all is because the NRL and clubs have pumped resources into developing NZ and the PI eligible players for the last 20-30 years and kept/made those nations competitive as a result.
If you want to point fingers at people for undermining internationals look no further than the English RL establishment, whom for at least the last 30 years, and despite tens of millions of pounds in investment in late 90s and early 00s, have self sabotaged so often and so consistently that they've effectively allowed English RL to slowly rot away to the point that it's not only a good chance of going semi-pro again, but that they've been totally uncompetitive on the international scene and have basically no locally developed drawcards and star players to draw the average punter outside of England through the gate. On top of that they've totally failed to help develop the game in their local region, particularly the Home Nations and France, to the point that they basically gave up and cut funding and any meaningful support about a decade ago.
You have to fix that if you want to fix internationals, and you don't do that by frivolously pumping money and resources into a short term one off event that will almost certainly have little to no long term impact on the sport's growth and sustainability in England and surrounding region, and then trying to shame the rest of the world into participating in the middle of a global pandemic and without any hope of reasonable compensation for the risk they are taking to participate.
How you do go about it is by investing in bottom up growth across the nation and increasing exposure of the top tier club competition. Now how you go about that in English RL's case specifically is debatable, but that is what's got to happen if you want to turn things around and for international RL to become relevant again.
