Similarly... I _really_ dislike clicking a link in Safari on iOS and it opening an App instead of going to the web page. I have the YouTube app installed and use it on occasion, but its really jarring when I click an organic search result in Duck and get launched into an app that may not have the same privacy settings my browser is setup with.
Pro tip, links clicked in private mode will always ask you before opening the app, so you can say no.
I end up just using YouTube through the browser and only installing the app when I need to download videos, e.g. for a plane trip, and then uninstalling it after I land.
Brave prompts you before doing that. Then you can long press to new tab.
Ironically, I have the opposite complaint with YouTube, particularly with these new Twitter web views. It takes 3 “navigations” now to get to the iOS YouTube app: one to open the Twitter web view, one to open that URL in Safari, then one to open at YouTube video in the native app.
