I haven't seen that many macs outside design departments in any big European company I have visited.
Some big companies such as Sony actually have Linux as their first choice, windows second.
I know this sounds silly or wrong, but most dont think of those as "Tech" Companies. Modern world uses of "Tech" now mostly means Software.
I think you are living in a bubble.
I am not, considering I am the only defending 5G and Ericsson on HN. But you should say that to the rest of HN.
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.
In fact our Java folks get macbooks as option, and eventually many of whom end up migrating to ThinkPads with Red-Hat/Windows, when starting to deal with complex workloads.
On the .NET teams everyone is on Windows ThinkPads.
