> Commercial solutions are interested in keeping users locked in and constantly upselling more features to them. As a result of that, you get notifications, features, popups.

At this point I'm pretty convinced that non open source software simply isn't viable for end-user applications and tools. The incentives don't work. You always end up with upsells/ads, insane missing features, bad UX, etc.

Closed source seems to work fairly well for some things like OSes, games, and perhaps some big-contract B2B, but not for apps.
