You say third party, but I think you mean proprietary. Essentially everything running on these devices is third party. Pine themselves aren't making PineChat and similar programs. Lack of support for proprietary apps is something to blame those proprietary app developers for, generally. They haven't given the people freedoms to port them. Matrix and XMPP are third party, free, and already usable on a PinePhone.
