Because companies keep bringing this fight.
Companies will naturally conclude they should just make proprietary software, which doesn't require a big fight. And I think that's a shame.
How many of these companies could exist if all these projects underpinning their own swapped to the SSPL, BSL, etc? And I don't mean now - once you reach a certain size, if you have to replace a bunch of dependencies, you have the resources to do it. But when these companies were smaller, would they have been able to create their own implementation of all these dependencies and still get their product to market? Would they have had the resources to commit to all of it? Would they have had the money to pay for non-FOSS options?
How many of these projects would still exist if the community couldn't commercialize them? We're not even talking about whether or not they ultimately end up contributing code back, etc., because it's not like these licenses give you some threshold of code contribution after which you can commercialize it. Sure, the possibility exists of some special private licensing agreement being struck, but that's possible with proprietary code, too.
Source available might sound fine from a personal use perspective, but it ignores the fact that the environment that made all of this possible would not have been possible under that model.
To me, the difference is that these are all building blocks rather than standalone products. I think of these commercial products as making sense for standalone services, rather than libraries and other building blocks.
But also: I think the business model that built all those open source building blocks has always been pretty shitty, relying on a lot of altruistic un- or poorly- compensated work from people. And I think that's bad. But I don't think demanding that companies making useful services also be subjected to a shitty business model is a good solution.
But, let's take just apache and nginx as an example: Lots of people offer just webhosting as a service. It's gotten less and less common now, with things like Squarespace, Shopify, Medium, etc. etc. etc., but once upon a time there were tens of thousands of companies that were making all their money by providing storage/compute/networking and a place to upload your HTML files, and then later adding in additional services like PHP and other scripting languages, MySQL for database hosting, etc.
Now, the context here is a bit different here, of course, particularly for Apache httpd. But Nginx has Nginx Plus, MySQL AB would license you a closed-source version or do the usual support/consulting/etc. stuff. But it's not hard to imagine a world where they could have easily said "Hey you know we're experts in running this stuff, we should just run it for people and charge them" - just like we see with a lot of these "open source" companies today.
There was never a general outcry about tons of businesses making money just hosting these open source services, even though the vast majority never contributed financially or otherwise to these open source projects. The only real difference I can see between then and now is simply what path the companies behind the projects, where applicable, have taken to monetize. Would the internet be a better place if MySQL AB moved to offering hosting as a service and put MySQL on the BSL, preventing all of these webhosting companies from having existed? If F5 had done it after acquiring Nginx? Cheap and plentiful webhosting is a big part of what grew the internet so quickly, particularly before the 'Web 2.0' days of social media sites centralizing so much of the traffic on the internet into a handful of places.

Well, I'm not demanding a company do anything. I'm just saying that the internet as it exists today, including all of these companies we're talking about, would not exist if earlier on people had made the same choices they are. Open source is not about guaranteeing a viable business model to companies - it doesn't care about your business - it's about ensuring certain freedoms in software. And the internet we're discussing this on exists because of those freedoms it guaranteed.
If you can't build a viable business when abiding by those freedoms for whatever reason, then sure - go build proprietary software. I'm not going to call it or you evil. But I do take issue with a company using open source as a method to gain adoption, additional contributions, mindshare, etc. and then no longer being open source while talking about how they are an "evolution" of it. You're not an evolution of open source if you're removing freedoms.
