Yes it does, especially when you remember the fact that developers are also consumers. But even if they (we) weren't, it would still impact consumers. I, android user who's completely ignorant when it comes to android development or even mobile in general, would be heavily impacted by this.
My custom youtube clients would never be approved by google. My (free) apps for watching anime and reading manga would never get approved by Google.
And something that's approved today could stop being approved tomorrow. it's up to Google / Microsoft / Apple to decide after all, they're the ones in control of our devices. If they stop liking my open-source ad-free minesweeper game, then I can't play it anymore. I'll have to download their bloated proprietary version with ads and a subscription to keep playing.
