That's the fault of (A) Electron and (B) developers who use Electron who (B.A) erroneously think that because Windows users don't mind having no menu bar then everybody else feels the same and (B.B) don't reimplement what Cocoa/Carbon give developers for free.

It's not macOS' problem if people seem to prefer writing mediocre cross-platform apps than proper, native apps with full support for macOS-specific features like system-wide automation, proper integration with the system pasteboard, Quick Look, accessibility features, etc.

Is it Gnome's fault that XTerm has shonky cut-paste behaviour? gnome-terminal works wonderfully.

Or is this the projector problem again: when you plug a mac into a projector and it doesn't work, people blame the projector. When you plug a linux machine in, people blame linux.

Of course it isn't GNOME's fault if xterm has shonky cut-paste behaviour, but that really only serves to back up my point — don't blame the system if one (or a handful of) apps happen to behave contradictorily to its conventions.

I'd never heard of the projector problem, but given Linux's unreliable track record with multiple monitors, I'm not surprised people blame Linux. The problem as stated doesn't define whether or not the projector is actually at fault or not, so we can only really start diagnosis where intuition leads us.
