Cryptpad is E2E encrypted. At a first glance, this is not.
Which also means its features won't be constrained by the E2EE architecture.
At a first glance, it seems the suite numerique wants to be simpler than full traditional office documents. It seems to compare itself with notion and outline.
CryptPad has very simple modules and also more complex, OnlyOffice based modules.
Ultimately, if the suite numerique's frontend is able to send editing patches as JSON, it should not be too complicated to make it work on a CryptPad server and make it E2EE, which is exactly what the CryptPad team did to OnlyOfficr (the "why not both" option)
