@mr_harm @libreoffice Yes, ind orgs can set defaults on their local install.
It’s a human factor issue. Imagine you set ODF as default, everyone is happy with it but someone sends an OOXML file from MS Office which doesn’t render right in EO - it’s the sender’s problem. Save in ODF.
If OOXML is “standard”, then people blame EO for not opening it right, mgmt get complaints, maybe even recant and go back to MS because “EuroOffice doesn’t work”.
ODF *is* the native format for most office suites. Forcing MS users to use ODF (because the rest of us are on LO/EO/OO) makes MS treat ODF compatibility as a first class format. Allowing Redmond to dictate the terms on which other office suites interoperate is a bad idea and will stymie adoption.
Obviously there are millions of old docs in MS format. EO needs to open them. Doesn’t mean new docs going forward need to make the issue worse.
