MS Licensing idiocy
So I have installed LibreOffice at home and am in the process of installing it on all work systems. However... I do some work for a local 3try level institution. They give away a 'free' copy of MS Office, and it's installed on school devices. Such as my school laptop. I have a 'personal' OneDrive (30 GB) and two 'business/education' OneDrives (1 TB each). LibreOffice works on files in all three OneDrives, and in Apple iCloud (2 TB) and in Google Drive (15 GB) and in DropBox (2.5 GB). Back when I had a 'personal' copy of MS Office, terminated years ago, it worked in my personal OneDrive, and, with effort, in iCloud and DropBox; I didn't have Google Drive then. It would complain that I needed to 'log in' when trying to access files on the 'business/education' OneDrives, and no, the 'personal' login wouldn't work. The school MS Office install will access files on the local drive, on the appropriate 'business/education' OneDrive, but insists on getting a 'login' on the other 'business/education' OneDrive and the 'personal' OneDrive, and no, the school login won't do.
MS wants me to get a fully installed, fully licensed, copy of Office 365 for my 'personal' OneDrive and a different one for the other 'business/education' OneDrive. This is not going to happen. LibreOffice works. Apple iWorks works (for certain values of 'working' for Numbers, possibly the worst app ever perpetuated by Apple). WPS works. WordPerfect Office works. I use MS Office on school equipment because the school insists; I use LibreOffice and iWorks (ok, Pages and Keynote, I really hate Numbers) for everything else. If LibreOffice worked on iPadOS I suspect that I'd stop using iWorks. For reasons of ideology LibreOffice is not available on iPadOS; Collabra is; Collabra is kinda-sorta a fork of LibreOffice only not as good, the day that LibreOffice works on iPadOS is the day that Collabra gets banished into The Outer Darkness, but I'm not holding my breath waiting. There will NEVER be new installs of MS Office on my personal systems, or at the office. The office OneDrive will probably go away sometime soon. I don't care. In the meantime I use MS Office on school equipment at school, and only at school. Notably certain 'portals' can detect if a file was done in, say, DOCX format using LibreOffice or Pages, and will reject them, so the most common use of MS Office is to open files I worked on using sensible software in MS Office, do a save as, and submit. And that means putting the file onto the school OneDrive, or MS Office will start bleating about needing a login.
MS is doing their very best to attempt to use their market position to try to force their crap, including CoPileOfShit, onto all systems. Not happening here. What they are succeeding in doing is to make some users avoid MS software at almost all costs.
The real reason why MS is screaming about reselling is that they don't get any money from the resale, and older versions aren't as restricted as newer versions, and, most especially, older versions don't have any CoPileOfShit. The harder they squeeze, the more users slip through their fingers. Bite me, Grand Moff Nadalla.
