Anecdotal of course but this isn't my experience at all, I don't know of any current or ex-colleagues that are working in offices at all. I think in southern Europe it's common to have more onsite.
I think there's a bifurcation between the startup/tech world, who indeed work a lot from home, and all the other tech workers in non tech industries (bank, insurabce, govt, corporate), who have mostly long since been recalled to office (in non US OECD countries).
