I agree with him. The typescript community is very unprofessional for going around spamming repos because some project they don't use or contribute too has removed their favorite language from the project.
Believe it or not, but JS vs TS really comes down to personal preference. Turbo is for client side JS and it used in a Ruby framework. Why is it so surprising that Ruby programmers want their other code built in a dynamic language?
If you work decades in a dynamic language you get good at maintaining, debugging, and developing in dynamic languages.
It's also worth noting that Turbo users don't interact with it via JS, it's whole purpose is to create interactive web applications without JS. You apply data attributes to HTML elements and the framework manipulates the DOM based on server responses.
A person using Turbo and upgrading to this version wouldn't notice a difference.
I think some of the vitriol hurled was over the top, especially given that folks can just fork the project and move on -- isn't that the whole point of OSS? If it were a closed source product it wouldn't have even necessitated much of an announcement. Disregarding the specifics of who worked on this, I think this sort of reaction can only be discouraging to OSS maintainers as a whole (much as I agree that the change wasn't handled great).
my guess is that's primarily due to the shift in incentives for social media, but also Svelte's decision being made by the group of maintainers/contributors together, and not impacting end users more or less at all as Svelte didn't stop generating types when they swapped from TS to JS+JSDoc
