BlueJeans and Zoom both don't require installing a proprietary application, so this isn't a problem I have ever faced. You don't need to lose clients; just don't install the app. Both support joining calls from a web browser, or dialing in from a phone number. Skype also has some kind of web client but I don't know if it does video calls, or only chat. You are setting yourself up for a moral dilemma that doesn't exist.
