It’s not such a joke for about 70 percent of the people who use a computer. All most people do is use the internet, write a document or two and check their email (most of the time using a web based service).
All of which can be done by any OS.
The only reason anyone would want Microsoft is if they specifically ran a program that required Windows … most will say that MS Word runs better on Windows which is true but most people I know write or view the most basic documents that any word processing software is more than adequate.
And even if MS word is required by your school or work … get them to pay for the OS and the word processing software.
Otherwise, the majority of the people I know with a computer only use it as a glorified tablet to access the internet and browse social media … all of which can be done with the most basic Linux distro that won’t hassle you with annoying popups asking you to do things you shouldn’t even be thinking about.
There is virtually no difference between running Word 2007 on modern Windows or under Wine, and I don’t need to use 365 (which is pushy about features in the Home tab and had a terrible redesign). I might pirate Office 2013 at some point if its compatibility rating increases. Still, I prefer LibreOffice unless I need to share the document.
