No, this is how change is driven. How do you think change happens? Getting a big committee together and getting buy in from all interested parties? That's not how it works. But maybe this is how it works, maybe this job board attracts a bunch of candidates who are tired of the status quo, and other candidates start telling the companies on other job boards that, sorry, but they're more interested in the companies that list on this particular job board, and those companies then see that the talent pool they're drawing from is smaller than it needs to be, and they decide they want to draw from the larger pool, so they change their practices, and then that snowballs, well maybe now you have industry-wide change.
I don't personally see this having much of an impact, but I think the people who started this are doing exactly what you're saying they should be doing, except that you're pillorying them for it because they aren't doing it through some impossible broad consensus approach.
> what other workers have to go through to get a job, we really do have it made, and this seems like a minor nuisance at best
It is true that we have it made, but I do not think it is true that we have it made in this sense. We have it made because our skills are very highly in demand and because of that, we are treated well and paid handsomely once we get a job. It is true that we should never ignore, down-play, or fail to appreciate this privilege, but that doesn't imply that we should not discuss or advocate for improvements where needed.
Where we don't have it made is in the predictability of employment once competence has been demonstrated. Other professions and trades usually have long-and-tedious up-front competence proving phases, but then they have a credential that will be respected by future employers when they have open positions. We are fairly unique in forcing people with long and distinguished careers to continually re-prove themselves. Our employers have open positions, but it takes a lot of pointless and duplicated busy-work for a competent person to slot into them.
I think what it comes down to is that our process is relatively mediocre, good, or even great for inexperienced unproven new entrants to the job market, but rather sub-par for experienced and proven folks. And that's why you see people looking for a better way.
