Everyone wants web apps to help sell hardware, right up until your app store grows into a money maker. Then the incentives are different.
Regardless, today's mobile systems are much better, web browsers are much better. It is much easier to write a web app that is functionally identical to native than it used to be.
Modern reality. Conversation rates for PWAs are higher than mobile apps because there is less friction in the installation process. Load times are often lower, which can be an overall superior experience. If I'm a small shop, trying to get on someone's mobile device, these items matter a lot. Also development costs are much lower when you can share code for your mobile app and your website.
The value add of being in the mobile stores is pretty minimal. Discovery is poor, search is poor, then there is constant churn in policies, submission process, APIs, development environments/languages, fees, etc. In contrast to this, the browsers hold very very high backwards compatibility. Churn will be in the support libraries or framework you adopt and not fundamental to the platform.
