Cannot speak for other schools in other countries (and I guess this question was targeted at colleges in USA), but I am currently studying Open informatics at Faculty of Electrical Engineering at Czech technical university in Prague and all the courses I have that are not mathematical, but require to use a computer do take into account that you may not be using only Windows, but also MacOS or Linux. I haven’t yet encounterered a software that we would be required to use and wouldn’t work on Linux, nor did I have to go through any more hassle because I use Linux, but rather contrary to that. In some cases using Linux made things easier and more straightforward for me.
