Summary: Richard Stallman gave this talk some years ago; meanwhile, a leading technical university got cracked due to Microsoft* and it won't dare mention the culprit
So Microsoft has dragged this university's computing environment down from world class to that of a year 2021 "Hillsdale College". To be sure, Oracle and Cisco also have their fingers in that pie and a role in the demise of the institution's role as one of the world leaders in computing. See "Our Attorney's Response To Microsoft" (posted by Roblimo) and this last article which brings up a very important point -- that Microsoft regards its contracts as trade secrets so even someone resourceful and tenacious would be unlikely to succeed in a FOIA request regarding the publicly-funded university's support contracts. Microsoft tried to censor information while crushing standards. Those institutions late in weaning themselves from Microsoft Windows can look at Samba 4 as an alternative.
Quit throwing taxpayers' money at Microsoft, especially when it fails to fulfil basic needs and instead facilitates espionage by foreign and very hostile nations
