I have observed over the years the IT/Tech tends to attract a lot of incredibly literal, grumpy people who do not like it when people take liberties with language.
For me as well the first content is strange, that "I've invented subscription". It is basically just applying an existing pattern from not-so-much-different other field?
indeed amazon prime is the same, gym subscription is the same etc etc. Not sure what justifies the "no one ever done it"
They hide behind “precision”, which is the other person’s fault when really they lack communication (griper’s fault).
The emotional labor of having to be fully responsible for precision is under-appreciated. That burden is where the grumpiness comes from.
