That was a nice feature, but there are other apps that do this without consent and I don't like it. For example, if you have the NY Times app installed and tap on a link in Safari that leads to a NY Times article, it automatically opens it in the NY Times app. iOS has no user controls for this behavior. The only way around it is to long-press on the link and pick "open in new tab", or uninstall the app.
Actually, it does but they are shockingly unintuitive and hidden. The best way to change your preference among supported link handlers is to copy a URL, paste it into the notes app, then long press that link and choose “open with” either safari or your preferred app. That will stick until the next time you long press a link in this way.
An iOS developer for JIRA taught me this when I submitted feedback that the JIRA app suddenly stopped intercepting links (probably because I had inadvertently long-pressed to open a link in safari, not knowing I was setting a preference by doing so)
