Since Standard Notes (SN) is part of Proton, it should really be included in subscriptions, at least the unlimited plan. (For an "unlimited" subscription, there seems to be a growing list of limitations; first it didn't include SN, now it also doesn't include Lumo AI.) In Standard Notes' 2025 update (https://standardnotes.com/blog/2025-update), they said:

What has changed since we joined Proton is our capacity. Being part of the Proton family means we can draw on the resources of a larger organization...

Why is Proton spending money and/or time improving another service that doesn't benefit its own users? It's strange that a proudly community-funded company is giving community funds to SN without any benefit to the community. A good notes app is missing from the Proton ecosystem, and I can't justify spending another $120 a year on SN to supplement a $288 a year subscription to Proton, especially when some of the money I've given to Proton is already going to SN!
