A small GPL library for, say, some statistics calculation, would mean an entire product's source code would need to be released if it used the library.
If the larger software is so much more expansive than the little GPL covered work and so valuable, then the commercial interest presumably has the resources to either write their own or license a commercial variant.
I find a lot of complaints about the GPL come down to "why can't I do what I want to do with your stuff?" and the obvious answer, started before the question is even asked, is "because that is what we don't want". It isn't one extreme getting in the way and being a bad guy, it is the two ends of the spectrum being incompatible by default. This can be dealt with amicably by either negotiation or moving on and leaving the other "side" to do their thing without you. IMO trying to frame it, as some very much do with comments about viral licensing and such, as good-vs-bad, is either naive, entitled, or bad in itself, or some mix of the three.
I feel most people don't understand that their projects are unbillable and "negotiating" is not an option.
If you project is avaliable through AWS/GCP console I could "pay" at my discresion.
If there was a clear price and billing details, I can email my boss and get it authorised
If something needs to be negotiated, we have to get senior stakeholders involved - those people don't move for less than 100k, you will never get paid.
Why do you want to negotiate? Large corps are burocracies. I can only get mine to donate to a registered charity, is your project one? To pay a bill is easier.
There are few people that have authority to negotiate and their time is expensive. If they spend two hours to "negotiate", they are charging a pile of money the company could have paid you instead.
Right, but making my code MIT won't get me paid either.
I will just spend more of my free time offering free support to some large enterprise that can't even figure out how to make a 1h negotiation happen without wasting boatloads of money.
That is a valid point in some cases.
But counterwise I feel that many people on the other side of this need to accept that in many cases the creator(s) of the GPL covered code simply don't want it used that way and that is their prerogative, and they don't agree with the assessment that either they, the project, or the world at large, would be better off some other way. In those cases billable or not is a moot point, as is negotiation for that matter and you will be rebuffed (hopefully politely, there is no need to be dickish about it).
