Then once the alternatives are no longer so viable, they use their dominant market share to their advantage and the detriment of users.

You are mis-construing EEE.
Theia is being developed by TypeFox, Ericsson, RedHat, ARM and more. Orion is being developed by IBM and more.
Both Theia and Orion are projects under the umbrella of the Eclipse Foundation: https://projects.eclipse.org/projects/ecd.theia https://projects.eclipse.org/projects/ecd.orion
The Eclipse Foundation (in the very most cases) does not develop software. They also usually do not pay developers. Their role it to arrange that companies and contributors play fair and nice when creating and using open source software.
At the booth, the VS Code people said that the reason it was closed was because it fell into the "services" umbrella, which has a lot of closed-source components. They did not have a comment on if it was going to be opened.

I don't see how someone else can leverage VS Code remote extensions to build something similar to VS Futures.
