Users who see the blog post section will know it is an SEO tactic, which puts people off. Also, nobody's going to read it; I would recommend adding some JS to detect if the user is a google bot, if so, remove the blog post. Lastly, the faceless, generic design can seem very sketchy.
Most ordinary people thing that they are just adding a shortcut to the website, whereas these wrappers convince the user they are actually installing an app app.
Personally I think PWAs are a bit confusing for consumers as they think "It's a website, i won't be able to use it offline." and if they get reminded that they can use it offline they usually forget.
