Another thing to mention regarding the web is that most people can easily install an ad blocker extension or install something like Brave browser to block ads on the web. Apps on the other hand are much harder to block ads in possibly using Pi-Hole or something more involved.

Regarding the “Hey, I released a new web app”, I have legit never used the word “web app”. Just call it a website instead and you will have a lot more interest without weird stares. “Web app” is a more techy term imo.
