I've never worked a software development job where I didn't have a company-provided machine that I installed Linux on. I installed the OS, I have root on the machine, I wiped it and returned it empty when I was leaving the job.
Lucky you, I guess. In all the companies I worked for I have had a company-provided Windows laptop where the OS was managed by IT. The degree of freedom (e.g. what software could I install, what websites were blocksd) varied.
