> Overtime, the most popular client will get a quasi-monopoly and will become incompatible with the rest of clients, no one will notice except for us nerds on HN.
As soon as those popular clients get incompatible, they cross the line into a new protocol - and we force them by law to open-source license that too. Sure, the major platforms will still own 90% of the traffic since the public is mindless (for now, until its educated over generations), but third party options will again be possible.
So all this advocating for protocols is still very relevant, it's just probably not going to happen by itself or from some magic invention.
