I’m using proton myself and have still continued to do so after these news. I kinda disagree that the founder is necessarily in any way maga or even a republican support just because he expressed praise for republicans on one particular issue. I think that’s taking it a bit too far, unless I’ve missed something where he clearly endorses Trump or his views more broadly.
Already done most of those, whatsapp is the hardest to replace for me from this category.
