I doubt it. "Walled" and "Safety" are getting confused here.
I think you like the App Store for its safety. You trust it, enough to be happy with it.
What does that have to do with wanting others to be denied alternatives? That deliver however much safety and different benefits that other people want?
If safety is one of Apple store's selling points, then competitive app stores will push Apple to deliver even more safety. Perhaps new forms of safety others pioneer. Apple didn't invent security or sandboxes. While also encouraging it to loosen non-safety driven (and therefore quietly non-customer friendly) restrictions on innovation.

That can only benefit you.
