As far as I know, Texas has not removed tenure. In 2015, Wisconsin significantly weakened their system and Georgia did as well in 2021. There was a paper published last year that discusses the impact of the political decisions on Wisconsin's university system that can be found here:

This does discuss the impact of essentially removing tenure, but the impact is also intertwined with budget cuts enacted around the same time. As a side comment, the good faculty that I know would absolutely favor a tenured job over a non-tenured.
