There's one thing that somewhat surprised me though: this line:
> "In 2018 Heroku was pretty much the only option for a newbie like me to get started with web-development"
Was it? Really? I mean, I'm not saying the author did anything wrong in choosing Heroku at the time (after all, who could have known back then what a dumpster fire Heroku would turn out to be), and the commercial success Heroku achieved before going down the gutter shows that it must have had some good reasons going for it, at least on paper before the users are confronted with problems that make them judge the situation differently…
… but I don't really get where that "pretty much the only option" vibe would come from. Maybe It's just me having completely different selection criteria, but from my perspective, there were lots of other options to "get started with web-development" and Heroku was just one among many. I don't see at all by what measure Heroku would have seemed like "pretty much the only option"?
