I use paid Protonmail but never the bridge app since I have no need for it. It make sense for business to hide some features behind a paywall. Almost all do. The reason they don’t need it for Android is because they already offer an app for it. That’s not the case for Desktop. Bridging 😉 to your next point of the other protocols; In tech you often can’t have all 3 - security, privacy, convenience, often 2 of 3. They created a service focused on privacy and security resulting convenience left behind in third place. That’s their business model, that’s what you get and the reason why you use them. If its too inconvenient then their service is probably not for you. They deemed those “established protocols” not compatible with their vision so they needed a workaround to keep your stuff secure and private. Otherwise whats the point if they are going to have such a blatant weak point of failure. If not you then many others will be complaining of the vulnerability that undue the whole point of using their services.
