I'll go with a poke at both sides.
As a curmudgeonly git I expect that whatever I type into an excel sheet* should stay exactly as I type it - until I do something about it.
Learning how to 'Format Cells...' isn't hard. Being a prima-donna about not learning to use the simple formatting tools is just unprofessional.
The first 20 years of desktop spreadsheets (visicalc onwards) had a lot of usage restrictions and yes formatting was a pain at times but at least you knew that the data you typed stayed as typed.
* I'd extend this to wordprocessors as well, underline in red by all means but don't change the letters I typed which may well be a correct technical reference or foreign word (or both).
