Sony Mobile is definitely a "modern tech company" and they are Ubuntu first. At the same time a company like Volvo or ABB is these days probably 60% software development and at most 40% mechanical engineering.
Industry/hard engineering companies here do tend to go Linux on their SWE machines, I've interacted with multiple SWEs from Volvo and Ericsson on some of my employers' projects (again, including pairing sessions) and none of them were Windows users. Mostly Linux and Mac.
Software companies do skew extremely into Mac territory, I really don't recall anyone ever using a Windows machine and very few run their ThinkPads with Linux, the vast majority have a Mac as a daily driver.
