This is some next-level dark pattern shit in System Settings. Click the info button to view the release notes for macOS Sequoia 15.7.1 and the modal window pre-selects the Tahoe upgrade for installation if you aren't paying attention.
@tylerhall I have noticed before, and I have been super careful around those buttons since Tahoe came out. I don't want to have to waste a few hours of my time restoring to Sequoia due to a small mistake like that.
