What endgame do you think your company has other than eventually selling out its userbase in one way or another ?
Riot is a Matrix client made by New Vector (https://vector.im), the company started by the team who originally created Matrix. The endgame there is to sell Matrix hosting (https://modular.im), support and other value-added services for Matrix. We are categorically not going to sell out our userbase - and we have no reason to; if we did, they’d just move to a different Matrix service provider.
It would be utterly sabotaging, and in the case of the Matrix Foundation, the Foundation is independently regulated by the UK Government as a Community Interest Company - and so anyone would be welcome to complain to the regulator (via https://www.gov.uk/government/organisations/office-of-the-re...) that the Foundation was breaking its charter, and the Directors would face fines and/or legal action.
This is why Matrix is in a fundamentally different situation to Keybase, or Zoom, or pretty much any other communication project out there, and why we spent so much time (and money) setting it up properly as a non-profit Foundation.
Matrix is 100% Free Software and you can run a server yourself.
