We already have regulations for accessibility and advertising. Yet they're weak in the US and rarely enforced.
That comment places a lot of blame where it doesn’t lie. It’s like calling surgeons extortionists for having the gall to charge for treating you. Yes, ideally that should be free and available to all, and perhaps if those people had the freedom to choose (e.g. having their own needs met so they didn’t have to work) they would do it. But that’s not how the system is setup, and their skills don’t translate to fixing the problem at the root. Not all of us are cut out to be politicians (and as we all know, being well-intentioned as one still doesn’t mean you have the power to enact policy).
FWIW, I don't consider surgeons to be extortionists. That's an absurdity that you are using as illustrative of why I'm wrong to call software developers extortionists when they charge for a privilege that should be a right. There are two issues with the comparison: 1) I did not call software engineers extortionists (but sure, I can see how you drew that conclusion), and 2) people absolutely should have a right to life-saving surgery and should not be denied on the basis of payment.
There is a huge preexisting problem: health care is not a human right [1]. There are other issues with health care that isn't just money. Many life-saving transplant patents are stuck in a wait list, for instance, and many die waiting. I do what I can. I'm a registered organ donor and try not to destroy my liver. I just haven't died yet, and I still need it. But this line of reasoning is off in the weeds, and I won't pursue it further.
Perhaps what it comes down to is that you have a pro-capitalist outlook, and I have They Live sunglasses.
What do you mean by "should be"? Surgery is free and available to everyone. So why would one accuse surgeons of being extortionists? So I am not sure how the surgeon comparison works. That example supports the parent commenter's point that these extensions should be free.
Of course, there is still the practical question of who will do the work and how they will make a living. We can do what we do for surgeons. Maybe have a nonprofit consortium that people fund, so that it can support the extension developers. Yes, people would be spending money either way, but at least that money would be going toward a larger cause. Just like we pay taxes so the government can fund surgeons, who can then treat people.
