Why a Premiere Pro alternative for short-form is a different kind of tool
Premiere and Montaj are not competing for the same hour of your day. Premiere is where a project lives for a week. Montaj is where a clip lives for twenty minutes before it is posted, and it is built around that assumption: no project manager, no bins, no render queue.
This is also why the comparison is not about privacy. Premiere Pro is a desktop application that works on files on your own machine, exactly as Montaj works on files on your device. Anyone telling you to switch for privacy reasons is selling you something.
