The problem is that someone always has to be in charge. If no one is in charge, usually nothing good happens.

So for example, we have Ecosystem A and Ecosystem B, each led by a company. Their users (note: NOT those companies) want an enhanced messaging standard between them. Who should be in charge of it? One of those two, or someone else? WHY would either company be incentivized to do so, since it hypothetically facilitates losing users to the other ecosystem? WHY would a third party come up with the best possible standard between these two (as well as maintaining it!) that they wouldn't then be compensated for?

So when you say "technology should serve the user", who or what "should" do this, and why "should" they do it? For free? You have to find or build the right incentives if you want something to be.

This is the same reason we are still grappling with a single medical records standard/exchange format. No one wants anyone else to be in charge of it, and yet someone must be, otherwise you have dilution of responsibility and perverse incentives.
