That's a poor take. The issue is that because there is no browser competition on iOS, Apple doesn't need to fear losing market share. That in turn ensures they have no reason to invest in Safari or web apps.
Apple has the staff and the budget to make a decent browser and to ensure web apps work, they don't because they don't want anyone competing with their AppStore or their 20b/year google search revenue.
