See How much does Microsoft Office 2016 cost without a subscription?One way to judge the strength of M$’s lock-in is to compare the price folks pay to be slaves to M$ rather than using FLOSS like LibreOffice which would cost them $0 per anything, forever. First they pay an unknown amount for the OS, the walls, floor and ceiling of their lock-in. Then they pay huge amounts for the privilege of using and creating documents on their PCs. It’s many $billions per annum to M$.
For many, ignorance is the key lock-in. Folks born and raised as slaves may not appreciate there is any other life. Slaves may feel any competition to their slave-master is a threat to their way of life. Education is key. Students exposed to FLOSS at school will certainly know there is another way, a better way to do IT. Students I taught even knew how to install GNU/Linux and applications like LibreOffice. Today, there are many more retail shelves bearing GNU/Linux and LibreOffice than the bad old days. The stats show it. LibreOffice has over 100 million users. GNU/Linux as the classic desktop and Chrome OS are slowly but surely taking share in the world. Android/Linux is kicking butt.
