But because of a language preference?
I specialize in AWS consulting + app dev. It’s something I’ve been doing for a decade, I know it well and I even did a 4 year stint at AWS working in the consulting department (full time RSU earning blue badge employee). But I wouldn’t refuse on principle to get a job that required me to spend all day on GCP or Azure.
[1] I really don’t understand burn out though. In 30 years across 10 jobs, when the “shit I have to put up with” got to high I would just get another job instead if toiling away
