Google does this even more egregiously with Android - my default browser is Firefox, but any links from Google News, Google Assistant and other Google software open in Chrome.
I wish Firefox provided two intents (does Android still call it that?), one for normal browsing and one for private browsing. Then any app that opens a link doesn't automatically get your active cookies from your main browser if you don't want it to.
Settings > Private browsing (under Privacy and security) > Open links in a private tab
An alternative is to use Firefox Focus (Firefox Klar on F-Droid) as your default browser, then its "open in" feature if you want to make it a permanent session.
Yep, Samsung camera will only open Samsung gallery, and will show a "Unable to find application to perform this action" toast if you uninstall it (via adb, because it can't be uninstalled via gui). Also it's the only app you can set to open by double tapping the home button, so you can't configure another camera application with the same ease of use.
They're doing a similar thing with the gmail app, at least on iOS. Practically everything now opens within gmail instead of the actual app. Google Meet links now open in gmail instead of Google Meet. I know they're both owned by the same company... but I don't want to give the gmail app microphone and video permissions.
