It is also a difference in culture, americans tends to praise themselfs for every small things as a big achievement. In other countries one would not even consider this as an achievement, just a standard iteration to explore.

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"
