"continuing to work on an already-shipped project is a very common mistake. Declare victory and walk away!" Maybe that's why we swim in the sea of barely done apps with terrible performance. It's time to demand quality of the app vendors. Uninstall facebook until it starts in 2s and works flawlessly. Use ublock until the ads stop slowing down a site. Uninstall any messaging app that cannot show you paginated history of messages, that is easy to search and to go back to given moment. Refuse to play single player games that require constant connection to vendor server. Maybe then these managers will learn that shipping A product is not an end. Shipping POLISHED product is.
