Sure, if your employer or client expects you to use a particular piece of software, you're more than likely going to use that software to meet their expectations whether it's Microsoft Office or LibreOffice. However, many people use office suites outside of these specific business arrangements and LibreOffice is there for them if they don't want to pay that $75 to $150.

Tying this back to the original discussion about device connectors, if Microsoft ever neglects Microsoft Office like it once did with Internet Explorer, I can see alternatives eventually overtaking Microsoft Office in the office suite market just as Chrome overtook Internet Explorer in the web browser market. In the USB-C vs. Lightning situation, Lightning is the Internet Explorer of connectors, the proprietary connector that has a much lower maximum data transfer speed and much more limited device compatibility than USB-C. Although USB-C is now the de facto standard for device connectors, just as Microsoft Office is for certain business use cases, neither is guaranteed to stay that way forever. If the design of the USB-C connector is unable to incorporate some important technological advancement, it will certainly be replaced by an alternative just like Internet Explorer was replaced by Chrome and just like Lightning is being replaced by USB-C now.

I do not really disagree with the points that were posted in response, anyway.

I just stated that "working in a country where MS Office is the de facto standard", all the other free alternatives (including Apple products - so it's not a dig against non-commercial products) are "not viable alternatives FOR ME" (special emphasis on the last two words).
