I don't know how else to say this but "Tough Shit"? Businesses are building their entire enterprise on the volunteer work donated by the free software community (or given away for free by some other company solving its own problems).
If you don't want 'your' SaaS to have downtime based on somebody else's whims, then fucking pay for your own developers (or your own AI) to build your SaaS platform in house. That's what IBM did in the 1970s, and nothing except market pressure is stopping you from doing it today.
I'm sorry for the vulgarity but this entitled attitude of businesses toward FREE SOFTWARE GIVEN TO THEM FOR NO MONEY is infuriating. If the electric company decided to give your company free power on windy days, would you then get angry that they installed a new model of turbine?
If they "depend" on people using their product, then surely all their paying customers will be happy to pay them whatever it costs to maintain the Zig-version-Bun that matters so dearly to them. They will see the folly of this rewrite and follow the money back to Zig.
This is a thread full of people saying they aren't convinced and would prefer to use Node/Deno, and that was enough for you to call them entitled and shame them. Your comment doesn't really read like a FOSS advocate, it reads like you're running interference.
Whether you like it or not, Bun actually does care about carving out an audience, and this thread has a lot of useful feedback for them on how they run the project. When people are concerned about the stability of your runtime, if the best defense that can be mustered is "tough shit, it's free," that's damning in itself.
I also think you overestimate the Zig fandom. We could be talking about completely different languages and the response would be the same because it's not about the languages.
There is a way to obtain software that comes with guaranteed stability and support and it's called a paid contract.
This is a completely off topic deflection. You make it sound like Bun rewrote the whole thing in Rust because they were financially in a corner, and if people just paid for free software, this wouldn't have happened.
Stability in JS ecosystem was never valued.
