When someone says "never/no one" in a casual conversation, they don't mean "it's physically and mathematically impossible for this to happen, I'm sure the chance of this is 0%". They mean: "the vast majority of people".
Techie communities can be tiresome with all the nitpicking.
I swear that if I posted a comment saying "nobody puts their dick in the vacuum cleaner shaft" while discussing the best vacuum cleaner design, somebody would feel the need to object and say they did it.
This lack of understanding of the general population is the issue.
I'm arguing that Tasker/Termux users aren't really your normal power users at all. Instead they are hackers, and would be satisfied by any form of stitching bits together to accomplish some task.
If Tasker/Termus didn't exist they'd be equally happy accomplishing the same things with custom hardware sensors or carrying a RPi around or whatever. They aren't actually doing anything useful with the software that couldn't be accomplished slightly less conveniently in other ways - the joy of the hack is the accomplishment.
When you view it like this, the market satisfaction argument looks different.
