@mos_8502 As a minority platform person (Unix/X), cross-platform software means that I get it at all. If Grafana was a program, it would probably exist only on Windows, maybe Mac as a distant second. Or cost a lot for Unix 'enterprise' stuff.
(I've been around my work long enough that I saw our paper account request forms, although I never had to process any. That too is 'cross platform' in a very basic sense of 'forms that can be filled out online on any computer of your choice'.)
