Better just to ignore the religious radicals sneering on the sidelines.
As others have noted Linux for home and Linux for work are two completely different things.
At work I use RHEL 7, packages 5 years out of date, don't have access to build tools to incorporate patches myself and a million and one other things I would never tolerate at home. Throwing some more money after a program that lets me not touch outlook sounds like a great idea.
At home I do none of the above things I can't think of a reason why I would ever touch a binary blob.
There are plenty of people who feel the same. Don't come into a hobbyist environment selling corporate solutions expecting a warm welcome. Instead of /r/linux go to /r/sysadmin or some such.
I have to use the proprietary bootloader for my newer machines and the wifi firmware the machines I haven't gotten around to replacing the wifi cards for yet.
About half of my machines are on coreboot and atheros cards.
Otherwise my user space is pure free software.
For games I play open source ones like 0ad when I have the time, which isn't often.
FOSS is a reality and is a great thing!
The point that was being made, was that promoting paid linux applications is a challenge. And that that challenge becomes more difficult because we need to operate in an environment where many of the biggest publications do not want to know anything about non-FOSS apps.
