Standard notes: what about don’t put all your eggs in one basket rule?

If the owner of the standard notes will now be a proton, doesn't that contradict this principle? I have a proton email account but I don't want it linked to my standard notes account. I don't strongly trust companies that offer packaged services like google or Microsoft. I prefer to have one service from one company. I am afraid that now I will have to change where I save my notes. What do you guys think about this?
