You footnote really describes why latex was not fine.

I recently wrote a thesis in typst. I have written other thesis in latex.

In latex i actually wrote in markdown and compiled to latex.

I don't need that for typst.

If typst can avoid enshittifaction over the next years, then I will stay with them.

You can still write in markdown and use pandoc to create typst.

The nice thing about Typst is that I think they've built up a community and business model that should disincentivize enshittification. The compiler is open source, and there's a large number of people using it now. If they start enshittifying, it can just be forked and maintained by the community at the very least at the level of functionality it's currently at, which is good enough for a large segment of people.
