All I see are people talking about consumer apps that could be websites, but it’s a problem in the business world, too. My small business makes a service for other small businesses and all our big competitors use apps for their system while we use a web app. Some even restrict to only iOS or Android, too. It blows our potential customers’ minds when they see that ours is just a website with at least as much functionality as the competition and the ability to access it from anything.
I have no idea why anyone would do it differently as it’s WAY easier/cheaper to maintain this website than deal with app ecosystems. And there simply aren’t enough users in this space to merit data scraping like with consumer apps.
