Well, if the federal government forced on messaging systems a requirement to interchange with other messaging systems, then some of this may be reduced? Back in the 20th century this was done for the voice-landline networks and in many ways has resulted in the only non-fragmented, multi-vendor, communications system we have today. GSMA was formed because of the fragmentation of the analogue cellular networks at the time, but inherited to a certain extent the regulatory requirements to interconnect.
XMPP held a certain promise there, but because there was no regulatory requirement, businesses just said 'screw this and lets keep our little nation states isolated for more money'. We saw this happen with both Facebook and Google. Other systems just made it difficult for apps such as Pidgin to talk to their systems from the start.
Myself I would welcome any move to interconnect, since I have 5 messaging apps just to be able to keep up with friends, since the favoured platform varies with region. SMS isn't the best, but most friends still have a phone number.
