Proton said the Standard Notes app, which is available for both mobile and desktop, will remain “open source, freely available and fully supported”.
It also suggested that there will be no change to Standard Notes’ prices; its press release specifies that existing five-year subscriptions “will continue to be honored.”
“Standard Notes will remain an independent product and in due course both companies will open access to their products to each others’ users,” Proton added.

I don’t think it’s trying to be a Notion or an Obsidian
