In the top left, there's an "open in app" button. It's not very intrusive, it's just sitting there in the header to remind you that there's an app. The rest of the website looks usable, right? Nope.
Click on "open in app": redirected to app store
Click on user's avatar: redirected to app store

Click on one of the reactions: redirected to app store
It's dishonest because the site isn't interactive at all -- there's a huge overlay that prevents any meaningful interaction with the site. It's quite the opposite of lazy, because there's a functional site under there, they just refuse to let people use it.
The article is talking about their financial struggles but they are too cheap and lazy to maintain multiple platforms?
Also, small pro-tip for anyone unaware. If you are on mobile web and on Yelp, but don't want to download the app, hold down the refresh button, and select 'Request Desktop Site' - this will load the non mobile version of the site that will not force you to download the app. The UI isn't as great as the mobile optimized site, but hey at least you can read reviews without being extorted into downloading an app.
