Its worse. Open source will be hijacked by hype warfare companies to extract free labour and build the things they want instead of the things we want.

But that's already what open source is...

Oh that ship sailed over a decade ago. Industry appeasement is a big part of what killed Drupal.

What killed Drupal, and what replaced it? WordPress?

The Drupal Association and its mismanagement of the community? I don't know how dead Drupal is, but I used to actively use and promote it and I have long since moved on, due in part to the Drupal Associations shenanigans.

I glanced at D.O the other day and was depressed to find they're reporting 400k active installs. I remember when that was 16M and growing. We're talking a loss of 97.5% of active sites. I'm betting the few that remain are mostly small government and nonprofit websites that haven't managed to put together the budget for a migration away from the platform. So yeah pretty dead. And yeah I blame the Drupal Association by way of Aquia and Microsoft. I left the project with a clear conscience after explaining in detail to an entire roomful of core developers that objectifying the codebase a la Laravel would kill the project stone dead within 5 years. Predictably they offered the typical "community developers are bad and don't want to learn" sneer as their primary defense of the decision. RIP.

But surely the death of any large chunk of PHP leaving the stage is cause for applause and boisterous shouts of joy?

Having coded back end projects in PHP, Perl, Python, and Node idk wtf folks who make comments like this are on about. Node took all of the worst aspects of JavaScript and spread them to back end development. Someone should have ended up on trial in the Hague for that particular crime against humanity and PHP is what you're grumbling about? Seriously?

I’ll grant you that there are good arguments in favor of your position. PHP, and then later JavaScript have both filled the world with more fragility and chaos than was necessary.
