Cluade is an Electron app because this is a cultural issue, not a technological one. Electron could make sense if you are a startup with limited development force. For big companies that want to make a difference, to hire N developers and maintain N native apps is one of the best bet on quality and UX you can do, yet people don't do it even in large companies that have the ability, in theory, to do it. Similarly even if with automatic programming you could do it more easily, still it is not done. It's a cultural issue, part of the fact that who makes software does not try to make the best possible software anymore.
